July 4th – Long Ditton, Surrey

My granddaughter and I were in the garden playing in her new sandpit when we heard raucous calls and squawks coming from somewhere up high in a neighbouring ash tree. Despite the racket they were making it took a minute to visually locate the perfectly camouflaged trio of bright green parakeets that had landed there. I’m not sure what the commotion was about, but they seemed to be a family, I think an adult female with two young ones demanding food.

Nowadays, sightings of these ring-necked, or more prettily named rosy-ringed parakeets, are commonplace throughout the county of Surrey, particularly in those leafy suburbs of Greater London lying closest to the river Thames.

Tales of how they first arrived and set about colonising the area are as colourful and as exotic as the birds themselves. One tells of a small number of the birds escaping from a film set at Shepperton Studios in 1951, during the making of ‘The African Queen.’ (which starred Humphrey Bogart and Katharine Hepburn, in case you’re way too young to remember that one!).

Another, less likely perhaps, but more appealing to me, is that they were released back in the 60’s by the legendary rock guitarist Jimi Hendrix, who allegedly brought them to Britain and released them, ‘ to bring some psychedelic colour to London’s skyline’, (perhaps whilst playing ‘Little Wing’?).

Then for our younger viewers, it is rumoured that a pair were released by the Blue Peter cast into the Blue Peter garden as recently as the 1990’s.

The truth of their introduction to British wildlife is likely to be far more prosaic and plausible. Parakeets have been popular pets since Victorian times and inevitably many birds will have escaped or even been deliberately released over the years, although the latter is technically illegal. A number of them are known to have escaped from aviaries across the south of England. During the Great Storm of 1987, some made their getaway from Northdown Park, in Kent, and it is rumoured that a piece of a plane’s fuselage dropped onto an aviary near Gatwick, giving more the chance to fly the coop.

Ring-necked Parakeet or Rosy-ringed Parakeet Psittacula krameri : Welsh: Paracit torchog

There is no doubt the parakeets are now well established in Britain and are recorded as our only naturalised parrot. In January 2017 the BTO estimate was of 8,600 breeding pairs and their status given as ‘introduced breeder’. The greatest concentration of numbers are in Greater London and Kent, with smaller numbers in Birmingham and Oxford and further north in Manchester. They are especially common in suburban parks, large gardens and orchards, where food supply is more reliable. The birds feed on a wide variety of fruit, berries, nuts, seeds and grain, have discovered bird feeders in gardens and have few natural predators here.

Until recently, the parakeets were generally considered a welcome addition to the county’s wildlife, and though their squawking and squabbling may have caused consternation to some, most people have enjoyed the sight of the colourful birds flying around. However, concerns have arisen about their population explosion and its potentially damaging effects on the country’s indigenous bird species, which has led to calls for stricter control over the colourful newcomers. In 2009, Natural England added the species, the UK’s only naturalised parrot – to its “general license”, meaning it can be culled, in certain circumstances – such as if they are causing damage to crops. The change gives them the same legal status as pigeons, crows and magpies.

As an occasional visitor to London, I love to see and hear them and they’re big, noisy, colourful and pretty to look at – a great way to get my two year old granddaughter to start noticing the local wildlife!

April 1st – Garden, Rhos on Sea

In the late afternoon sunshine a number of little bees were zooming around in a corner of the front garden, pausing frequently but briefly on the warmed surfaces of ivy leaves. I have seen similar ones here each spring for the last five years, so was pretty sure they were male Tawny Mining Bees, but I had to wait a while for a prettier and more distintinctive female to take a breather from her nest-building labours to be sure. Males significantly outnumbered females here this afternoon, probably because they don’t contribute in any way to constructing nests or to raising offspring, so once mating is accomplished by a lucky few, they are free agents.

Tawny Mining Bee – Andrena fulva

The rich fox-brown colour and furry coat of the lovely little Tawny Mining-bee (Andrena fulva) makes it the most distinctive and obvious of all the Spring-flying solitary bee species. It is a common bee in much of England and Wales, which nests underground and leaves a little volcano-like mound of soil around the mouth of its burrow. Nests can often be seen in lawns and flowerbeds in gardens and parks, or in mown banks and field margins in farmland and orchards.

Description

Size: Females 10 to 12 mm and males 8 to 10 mm long.

The Tawny Mining Bee is a small rich gingery-orange coloured bee that can often be seen visiting its nest in grassy areas such as lawns during the springtime.

Females are larger than males and covered in a dense layer of fox-red/orange hairs. Their underside is black.

Tawny Mining Bee female

The males are quite different to the females. They are much slimmer, covered in less dense orangey brown hair and have a distinguishing pronounced moustache-like tuft of white hairs on the lower face. They play no part in nest building or providing for their offspring.

Tawny Mining Bee male

When to see it

The bee has a single flight period each year and is on the wing from early April until early June; the males emerging well before the females.

Peak activity coincides with the flowering periods of fruit trees such as Pear, Cherry and Apple and also of fruiting shrubs such as currants, gooseberries and other Ribes species and are important pollinators. The female collects pollen and nectar for the larvae which develop underground, each in a single ‘cell’ of the nest, and hibernate as pupae over winter.

Habitat

Tawny Mining Bee feeding on Alexanders

The bee is common in gardens, parks, calcareous grassland, orchards and on the edges of cropped agricultural land.

Andrena fulva nests are constructed in the ground, and the nest entrances are surrounded by a volcano-like mound of excavated spoil. Nests are often in loose aggregations in tended lawns, flower beds, mown banks and in sparsely vegetated field margins. Pollen is collected from a wide range of plants including flowering trees and shrubs, weeds and garden species.

Life History

Having hibernated through the Winter, Tawny Mining Bees emerge in Spring as adults; the males emerging well before the females. After mating, the female seeks a place to make a nest. The bees’ tunnelling throws up small heaps of waste soil, that look like tiny molehills or volcanos with the entrance/exit hole at its summit. You may notice these little heaps in your lawn without associating them with the bees. They won’t spoil your lawn! The nests are short lived and do not damage plants or harm earthworms.

The bee’s mining throws up small ‘volcano-like’ heaps of soil with an entrance at the summit

Nests will often consist of one small, main tunnel, with perhaps 5 or so branches, each containing an egg cell. The nest is a vertical shaft 200 to 300 mm (8 to 12 in) with several brood cells branching off it. The female fills these cells with a mixture of nectar and pollen, on which she lays one egg in each cell. The larva hatches within a few days, grows quickly and pupates within a few weeks to repeat the cycle as new adults emerging the following spring after hibernation.

Sometimes more than a hundred females build nests in a few square metres but the Tawny Mining Bee normally does not create a colony: each female has her own nest.

Distribution in Europe

According to BWARS, the Tawny Mining Bee is common across most of England and Wales, there is only a single confirmed Scottish record, and only old, tantalizing records from Co. Kilkenny in Ireland. On continental Europe, the species is widespread and common from Britain eastwards across central Europe. It is not found in Scandinavia and is restricted in the Mediterranean region.

April 7th

Checking up on the Tawny Mining Bees today I noticed a number of the diagnostic little ‘volcanos’ have appeared in the bare line of earth between the lawn edge and the ivy-covered front wall.

Female Tawny Mining Bee covered with dusty earth from her nest

I spotted females going in a few times and there are still males hanging around close to the nest sites. I photographed one female as she had emerged from her nest, her legs, head and furry body coated with a layer of dusty earth.

As this garden is having a bit of an overhaul at the moment, there are very few flowering plants for the bees to nectar on, so they are having to seek food elsewhere. Poor things must be worn out, all that digging, producing eggs and having to fly across the road to find food.

An Enemy in the Camp

The bees carried on industriously, seemingly unaware they were being watched by a potential murderer of their offspring. The sinister character, a Bee-mimic, looks a little strange; it has a long rigid proboscis at the front of its head which it uses to tke nectar from flowers while hovering over them and long trailing legs. They are also quite cute, furry, lovely to see and entertaining to watch – this was a Bee-fly Bombylius major.

Bombylius major has several host species, including beetle larvae and the brood of solitary wasps and bees particularly digging bees such as Andrena, like our Tawny Mining Bees.

Bee-fly using its long legs to flick her eggs into the Tawny Mining Bee’s nest

The Bee-flies mimic bees to allow them to get close to the bees nest entrance. When close enough, the female will flick her eggs into or near the nests of the host insects. The larvae will then hatch in the nest and feed on the food stored, as well as on the young solitary bees or wasps.

I knew this is how Bee-flies behaved, but hadn’t witnessed their egg-flicking behaviour before today. I have to admit it is fascinating, while feeling a bit sad about the possible outcome for some of the poor hard-working Miners. But then I like to see the Bee-flies too…..

February 17th

Rhos Point will soon become a quieter place as the wading birds that arrived during last late Summer and the Autumn leave us and head back to their more northerly breeding grounds. Each year Turnstones come in a fairly consistently sized flock of about 60 birds and I think it’s likely that a more unusual visitor – one that draws birdwatchers here to search for it – arrives amongst them; the Purple Sandpiper. I’d met people claiming to have seen them here earlier in the winter, but I hadn’t had even a glimpse. Until today. Taking my baby granddaughter out for some very fresh air on the Promenade, as always with one eye scanning the shoreline and one watching where I was steering the pushchair, I’d noted the tide was on the turn. Only a strip of the rocky shore below us was exposed and yet there were two people walking along it, chatting and following behind their loose and randomly wandering dog. I wasn’t thinking kindly about this as a) I don’t understand why anyone would risk their dog injuring itself on the slippery uneven surface and b) why they don’t notice or seem to care about the disturbance to any feeding birds. But in this instance they were quickly forgiven as the dog flushed a single elusive Purple Sandpiper from where it had probably been resting on the lower rocks of the rip-rap sea break.

It didn’t go far, just across to the smaller rocks on the edge ot the water where it stayed.March 1st

Having now seen where the Purple Sandpiper had been lurking during high tides I went back to try to see it again and whether there may be more of them. I’d waited until the tide was at its highest and soon spotted the Turnstone flock quite high up on the rocks

I enjoyed the lovely close sighting of these gorgeous little birds, but really wanted to see Purple Sandpipers. And there he was, on the edge of the group and still apparently alone.

A lonely little Purple Sandpiper. I stayed and watched for a while in case any others popped up, but no. He was the only one. I walked a little further on, still searching, but found only two Redshanks. Again, lovely close up view of great birds, but not the colour I was looking for.

PURPLE SANDPIPER – Calidris maritima; Welsh: Pibydd Du

The Purple Sandpiper is a winter visitor to almost any rocky coast in Britain and Ireland. They are widely distributed around the coast though they are most abundant in the northern isles – Orkney and Shetland and along the east coast of Scotland, north-eastern England and Devon and Cornwall and scarce elsewhere.

The Purple Sandpiper is a medium-sized wading bird, slightly larger, stockier and darker than a Dunlin. It is mainly dark grey above and whitish below. It has a slight down-curved beak and distinctive short bright orange legs. In flight it shows a thin white wing-stripe on otherwise dark wings.

Above photo: January 28th 2012-Purple Sandpiper with Dunlin – Rhos on Sea

World Distribution: BREEDS Arctic & Subarctic Eurasia & North America, WINTERS: south to S Europe and Southern US.

Diet: Invertebrates, also some plant material, often feeds on rocks near tide edge.

March 2nd

Back again for another look. I didn’t even have to search for myself as a serious photographer, in full camouflage kit and sporting a super-long lens had him in his sights, saving me the effort. Today he was completely alone, with not even a Turnstone for company. He was quite lively though, having a good preen then skipping around the rocks, splashed by sea spray and totally in his element. Still sad to see him all alone though.

Closer views of the active bird today better show the purplish tint to the plumage that gives the species its name.

Maybe next year he’ll bring some friends.

Purple Sandpiper is currently AMBER listed in the Birds of Conservation list based on a Non-breeding Population decline by more than 25% but less than 50% and a UK breeding population of less than 300 pairs.

January 20th – Little Orme – Upper reaches

I‘d spent longer watching the seals than I had intended, so almost talked myself out of doing some proper walking and heading up to the summit. It was cold, the sun was already sinking lower in the sky and I knew the upward tracks were going to be muddy. But one of my aims for this outing had been to check to see whether or not the cormorants had begun nesting yet, so onwards and upwards it was.

At the bottom of the steep upward slope, Rabbit Hill to locals, a bird sat perfectly still at the top of a smallish ash tree. The sun in my eyes was so bright I could only see it as a black shape, so made another assumption that as this is about the highest point on this windswept clifftop and a favoured perch for crows, magpies and jackdaws, that it was a corvid. Only when I lightened up the photograph I took did I realise it had been a Kestrel.

The bracken and brambles that covered the slope to the landward side of the track have been cut back hard; this vegetation provides cover for a variety of small birds, including resident Stonechats and Whitethroats that come here for the breeding season. I’m sure it will have grown up again by the time they arrive.

I was right about the mud! It was almost take one step forward and slide back two. I pictured my walking pole lying uselessly in the boot of my car. I should use it more often, but it gets in the way when I want to stop and take a photograph. I took a breather to turn and photograph the view; no matter the number of times I have done it, it’s just so amazing I can’t resist. The spit of land projecting finger-like into the sea is Rhos Point and despite the hefty sea defences I know it has in place, it looks so vulnerable from here, perhaps more so to me because it’s where my daughter and her family lives and I can pick their house out from here!

At the top of the slippery slope is a levelled area where much of the stone was quarried out. The cliff wall at the back of this now grassy area is Jackdaw city, with many pairs of birds nesting in its nooks and crannies. You realise how many of them there are when the Buzzards glide into the airspace above and numbers of them suddenly zoom up and surround them, determinedly driving it away while making a heck of a racket.

(click on image to enlarge)

Herring gulls often join in the mobbing party too; it may seem that they prefer roofs and chimneys to nest on, but some do prefer the more traditional option of a bit of cliff. It’s interesting that although they may rob other birds of their eggs and chicks, they’ll join forces to drive off any potential predators of theirs. It’s not too clear from my photograph who’s who, but one Buzzard is very slightly left of centre and the other approaching the far left, with defending birds approaching mainly from the right. Poor old Buzzards, every other bird picks on them, even much smaller Starlings!

The edge of the cliff is crumbly and eroding but is a favourite spot for Jackdaws to sit and look down on the lower levels of the headland. There were several pairs sitting doing just that this afternoon, probably ones with nest sites nearby on the cliffs of the lower level.

I took a photograph looking down into Angel Bay from up here; it looked as though quite a number had moved off.

One of my favourite sights is golden gorse flowering against the background of a blue sea.

It’s always sad when a tree dies, but the skeleton of this Elder is now beautifully adorned with lichens and a fungus, which I’m sure is now past its peak. I’m not great on fungi, but I do know the one most closely associated with the Elder is Jew’s ear or jelly ear Auricularia auricular-judae; is it that Annie? I wish I’d seen it earlier.

The grass up here is grazed by sheep and further nibbled by rabbits, so is always neat and well-groomed. The path curves into this small clearing that looks almost like a cleverly landscaped wild garden designed to lead you to the stunning vista.

click on image to enlarge

The nearest rounded hill is Bryn Euryn which I’ve walked you around many times and shown views from there to here, but you can see they would be a fairly short flight away from one another for Buzzards, which nest on Bryn Euryn, and Ravens which regularly overfly both.

Some of the hawthorns here still have good crops of berries.

And there is lots of glorious golden fragrant gorse.

Another wider view from higher up over Colwyn Bay and towards the Clwydian Range of mountains where Offa’s Dyke begins.

The low sun gives a wonderful texture to the rough grass and rocks. I always wonder how rocks such as this one arrived where they are, but this one I use this one to recognise the point where I leave the path and approach the cliff edge, extremely cautiously, to get a better view of the site of the cormorants’ colonial nesting site.

They don’t appear to be doing much yet, in fact there were just two there when I first looked, although a few more did fly in to join them as I watched.

The Great Orme – click to enlarge

I climbed up a bit higher to admire the view across Llandudno Bay to the Great Orme. The pier looks toy-like against its great bulk.

The sun had dropped further and was almost hidden by the highest part of this headland to my left. The view from here is across Llandudno town to Anglesey and the bulky headland of Penmaenmawr. If you were looking at this as a walker of the Wales Coast Path travelling in this westerly direction, you could roughly trace your onward path and see where you would be in a day or so’s time.

Llandudno Bay, town and beyond – click to enlarge

Low light lends a different atmosphere to this place, especially when you’re alone and have an imagination such as mine. Rocks cast shadows and a solidity not as apparent in bright sunlight. I wonder how it looked before its bulk was reduced by quarrying? Are these squared off rocks remnants from that time or were they deliberately placed before then for some other purpose.

The remnants of a dry stone wall lead the eye to the wonderful view.

click to enlarge

Then there are Hawthorn trees, contorted into wonderful shapes by the strong prevailing winds and features long associated with tales of witches and magic……

Even in broad daylight I wonder about the spot in the image below. I can easily imagine as some kind of mystical meeting place guarded by the trees and I know that as a child I’d have found a way around the fencing and sat on the top of that little hummock letting my imagination run riot, most probably giving myself nightmares.

I fancy other mystical markers – a hawthorn branch heavily covered with lichen that reaches out over the track and frames the view.

and a little tree well covered with lichens and further embellished with sheep’s wool.

The atmosphere is further enhanced by a pair of Ravens, companions of witches and wizards, ‘gronking’ as they passed overhead.

And a rabbit, moving strangely slowly around behind the wire fence. It didn’t bounce away from me like rabbits usually do and I wasn’t sure if it was just old or not well; its eyes looked strange and it may not have been seeing properly, if at all. It put me in mind of rabbits we used to see years ago with Mixomatosis, but is that still around? (see footnote)

A chaffinch foraging around in the gorse and blackthorn scrub led my eye to this sunlit spider’s web and distracted me from further over-imaginative thoughts!

Had a bit of a slithery walk down Rabbit Hill then headed back to leave the site. I took the path closest to the cliff edge to avoid oncoming late afternoon dog-walkers and spotted this bird sitting on the top of a gorse bush seemingly looking out to sea. Once again the sun was obscuring it from proper view but there was no mistaking this was a Kestrel, a young one I think. It was very cold now but the bird was sitting perfectly still with its feathers fluffed out.

I risked walking back around to get some better lighting, expecting it to fly off, but although I think it was aware of me it stayed put. I did get to a point with a better view – and the camera battery died! Time to go.

More about Myxomatosis

When I wrote this post and mentioned the ‘poorly’ rabbit I had seen, I hadn’t realised that the horrible disease, Myxomatosis, was still present and affecting rabbit populations in the UK. As a country-bred child back in the ’60s, I remember seeing many affected rabbits which I found distressing, and as the poor rabbits were sick they were easily caught by our cats, who didn’t kill them, but did bring them home. I also didn’t know then that it could be passed on to pet rabbits; now they must be vaccinated against the disease.

The disease called Myxomatosis reached the UK in 1953, where the first outbreak to be officially confirmed was in Bough Beech, Kent in September 1953. It was encouraged in the UK as an effective rabbit bio-control measure; this was done by placing sick rabbits in burrows, though this is now illegal. As a result, it is understood that more than 99% of rabbits in the UK were killed by the outbreak. However, by 2005 – fifty years later – a survey of 16,000 ha (40,000 acres) reported that the rabbit populations had increased three-fold every two years, likely as a result of increasing genetic resistance, or acquired immunity to the Myxomatosis virus. Despite this, it still appears regularly at rabbit warrens.

If you’ve never seen an affected rabbit, I can’t stress how awful it is. Initially the disease may be is visible as lumps (myxomata) and puffiness around the head and genitals, which progresses to acute conjunctivitis and possibly blindness; this also may be the first visible symptom of the disease. The rabbits become listless, lose appetite, and develop a fever. Secondary bacterial infections occur in most cases, which cause pneumonia and purulent inflammation of the lungs. In cases where the rabbit has little or no resistance, death may take place rapidly, often in as little as 48 hours; most cases result in death within 14 days. Not a good way to die.

Wild rabbits tend to recover quickly once the disease has passed; a certain density of rabbits is needed to keep the disease going and once the number of rabbits drops below that level the disease will disappear until the rabbit numbers increase again.

January 20th – Little Orme, lower level

When the first sound I hear on my approach to the Little Orme is that of a Raven gronking, I take it as an omen that this is going to be a good walk! And so it was today – the old Raven perched high on the edge of the cliff, proclaiming his territorial rights, his distinctive call echoing off the surrounding rock. As yet there were no signs of Fulmars having returned to begin claiming nesting spots on the cliff below him. Notoriously noisy, they too would have been heard before being seen for sure.

Ears being more effective than eyes on this bright winter afternoon, I heard birdsong emanating from a small nearby tree. I didn’t recognise the song at first and with sun shining directly into my eyes, it took a couple of minutes for me to recognise that the singer was a Great tit. I edged slowly towards him, circling to try to reach a point where the sun was less blinding, expecting him to spot me and take off any second, but he was confident and intent on his purpose and chose to ignore me. I was delighted, I don’t recall ever being this close to a singing Great tit before and was impressed by his tuneful renderings.

He was indeed handsome and as the test of a male Great tit’s virility is displayed in the strength of the black markings that run from his throat to his nether regions, this one looks like he’d be quite a catch.

The ground here was frosted and in shaded places the grass was crunchy underfoot, but a pair of blackbirds, feathers fluffed out against the cold had found a more insulated mossy spot and were out hunting worms. I wasn’t sure if the female was deliberately collecting nesting material or if I’d disturbed her whilst probing and the grass had stuck to her bill.

Close by a Robin was singing quietly, almost to itself as it perched low and spied, head cocked, for insect movements on the ground below.

Reaching the cliff edge which overlooks Penrhyn Bay, all I spied was a distant single cormorant. (Well, I assumed it was a cormorant, but a sharp-eyed friend pointed out it was actually a Shag – so really happy about that as I see far fewer of them.)

A closer look shows the Shag has a narrow bill and a steeper forehead than a Cormorant and also lacks the white cheeks patches of the latter. A lesson learned, I will look closer in the future and not make assumptions!

Sitting atop the rocky mound that forms one edge of Angel Bay were a pair of large black birds. One had his back to me, looking out to sea – Ravens, surely? As I approached they flew down almost to the base of the rock.

Feathers gleaming with shades of purple and green they are magnificent birds, but you wouldn’t want to be on the receiving end of that enormous dagger-like bill.

As well as local folk, people come here from miles around in the hope of a sighting of the Grey Seals that have claimed Angel Bay as their own. Today I was one of a small crowd of spectators that were given a real treat; there must have been at least 40 of them ranged along the tide-line the whole length of the little cove.

Perfectly camouflaged to blend with the rocks and pebbles here, it takes a few minutes to get your eye in and work out which shapes are animal and which mineral. I make a total of 20 in the image below.

At first glance there didn’t seem to be much activity other than sleeping going on, but sounds arising and a closer look reveals that here and there things were not entirely tranquil.

Some see rocks as a sun-warmed resting place

while to others they are just obstacles to be overcome; going over the top must be easier than getting someone to move.

These two took to the water, they could be a male and a female as one appears smaller than the other.

They started off peacefully enough,

but things soon started to get a bit rough

and developed into what appeared to be a serious display of aggression or power assertion of some kind. ( I wasn’t entirely off-track here, but it has been pointed out that this was quite likely mating behaviour. I thought that mating happened sooner after the birth of the pups.)

Their interaction was quickly dissipated though when several more seals lumbered from the shore, showing a surprising turn of speed, and entered the water with much deliberate splashing.

Then sped off with purpose, keeping their heads above the water

to check out two kayakers that had paddled into the bay. The guys in the boats must have been thrilled to have had a close encounter with at least eight curious seals.

Back on the shore another pair having a bit of argy-bargy

this time more vocal than physical.

And that is where I left them to get on with their day while I got moving to warm up, with one quick last look over the edge of the cliff from the other side of the bay.

On the far side of the bay I scanned the cliff for any signs that the Ravens may be re-using the nest site that has been occupied for years. There was nothing I could see, but there were plenty of pairs of Jackdaws that seem to have already claimed or reclaimed holes and ledges on the cliff wall. Jackdaws are so numerous here that a black bird of a certain size usually registers subconsciously as such, but again it was hearing different sounds called by a small group of four black birds flying up that alerted me to the presence of the far less common Chough.

More wary than the resident Jackdaws, the presence of Chough, probably visiting from the Great Orme that forms the other side of Llandudno Bay, always takes me by surprise and that is my excuse for failing to get a decent photograph! That and the fact they soon spotted me standing out in the open pointing a long lens at them, so they took off and disappeared over the cliff edge. I have seen and photographed the pair below feeding here before, quite distinctive with all their leg bling, but the one above has none yet. Is that because it’s a young one I wonder? Please tell me if you know.

I couldn’t leave this lower level of the reserve without a nod to a Jackdaw, whose home this really is, so snatched this just before a dog followed by its owner sent him off too.

Waders v Weather

Colwyn Bay, on the Irish Sea, has big tides and at some high tides water levels can rise by 8 metres or more. On windy days big waves are driven in and as the tide reaches its highest point they crash dramatically, in places causing spray to rise and splash over the sea defences. Regardless of the weather, for the gulls and wading birds that feed here it is business as usual. For people, walking along the promenade on such days can be hard work and exhilarating, but for the birds that feed here on Rhos Point it has to be business as usual and whatever the weather or state of the tide the birds know instinctively exactly when to arrive and depart to best take advantage of fresh deliveries or deposits of food.

Interested to see how the birds responded to challenging conditions, I took these photographs on an exceptionally windy day when the incoming tide was set to be particularly high.

12:51 – Curlews begin to leave.

12:52 – Most of the oystercatchers that feed here don’t travel far, passing the time between the tide-turns gathered together on the rocks of the seabreak in Rhos Harbour, a short flight away. Some linger longer than others.

Herring gull, Oystercatchers, Turnstones and Redshanks

12:53 – A group of Turnstones all facing towards the incoming water

12:54- Big and bulky, Greater Black-backed gulls seem impervious to the rough conditions.

12:57 – This photograph of an adult and juvenile Great Black-backed gulls cries out for a caption doesn’t it? I’m leaving it to your own imaginations though.

12:58 – Turnstones on the sea edge, most standing on stones to keep their feet out of the water.

12:59- Another Curlew leaves, calling to announce its departure.

12:59- Turnstones and Oystercatchers. Interesting that they are all facing towards the incoming water but weren’t actively foraging for food. I think they are all facing into the wind, which would make them more aerodynamic and streamlined so they don’t get blown over.

13:00 –

13:03- Smoothing feathers ruffled by the wind back into place.

13:05 – A Turnstone takes a bath, or is that a jacuzzi?

Turnstone rock- hopping to higher ground

13:07- The Turnstones are more-or-less gathered together now. They are difficult to count as they merge so well into the background of small rocks, but I got up to about 56 individuals and I’m sure there were others behind rocks and one another, so the actual number is probably 60 plus.

13:08- Some Oystercatchers are getting restless, preparing to go while others seem in no hurry

13:12

13:18- As the tide encroaches some begin to leave

But the turnstones stay put, despite the rising water

13:21- A Crow arrives and announces his presence loudly

13:23- Another Oystercatcher is ready for the off.

Some stay and scrutinise the water for any last-minute tidbits

13:25: The Turnstones seem unperturbed by the water rising up around their small rock islands

and are the last birds standing.

13:45- The water has covered the Point.

13:46

Black-headed gulls are the only birds still flying. Low to the surface they seem to positively enjoy the rough conditions.

13:50

13:53 – The bigger gulls are unphased by the rush of the incoming tide and rather than fly away simply allowed themselves to be launched onto the water and rode the waves.

13:54- Wind-driven waves smash onto a flight of concrete steps and shows how high the water would reach if the rip-rap defences were not there; those steps below the middle are worn smooth and their edges rounded by the regular scouring of the waves.

May Bee Appearing on Ivy near You

BWARS, importance of ivy to late summer insects, Ivy bee, ivy flowers, small bee on ivy flowers, solitary bees

I know our native evergreen climbing ivy can be a pain in a garden, but at this time of year when it’s flowering it is a magnet to a wide variety of late-flying insects. To one particular little bee that has set up residency here in Great Britain in recent years, it is vital.

October 6th

It’s always exciting to see a ‘new-to-you (or me) species on your own patch and this week I had my first sightings of a little solitary bee I have only recently become aware of. It is commonly named the Ivy bee, as its emergence is set to coincide with the flowering time of yes, you guessed, the common but invaluable to late flying insects Ivy or Hedera helix, on which it feeds.

4/10/16-First ever sighting of an Ivy bee-Colletes hederae

Ivy bees are found in Austria, Belgium, Channel Islands, Croatia, Cyprus,France, Germany, Greece, Italy, Luxembourg, Netherlands, Serbia, Slovenia, Spain and Switzerland and are recent arrivals in Great Britain, but spreading and establishing fast.

BWARS – The Bees, Wasps & Ants Recording Society has been mapping the spread of the Ivy bee since its discovery in Britain 15 years ago. They say:

Colletes hederae was recorded as new to Britain in 2001 when Ian Cross discovered specimens at Langton Matravers in Dorset. Since then, the bee has spread across much of southern England (as far north as Shropshire, Staffordshire & Norfolk) and into south Wales. It is now extremely plentiful in some coastal localities, and increasingly, inland. Peak activity matches the flowering period of its key pollen forage plant, Ivy (Hedera helix), and the species is on the wing from early September until early November. This makes it the last solitary bee species to emerge each year.

Where to find them

Ivy bees like patches of flowering ivy in sunny spots, often in gardens.They look like small honeybees but have an orange-yellow striped abdomen and a furry ginger thorax, so they are quite noticeable as they bustle over the green balls of ivy blossom. If there is a nest site nearby you may see several of them on the flowers at any one time.

Ivy bee lifecycle

Unlike the larger honeybee, which is a social insect and has queens, drones and workers, the ivy bee is solitary. They are mining bees and after mating, a female Ivy bee digs out a burrow in loose earth or sand, and creates underground chambers. She then lays several eggs which she stocks with pollen to provide food for the larvae when they hatch. Although each female ivy bee digs her own burrow, tens or even hundreds of females nest close together in colonies, usually on sandy banks.

As with many insects, the mating process may be a brutal affair. Male bees wait by the burrows for females to return, then ambush them. Many males may attempt to mate with a single female in their quest to sire the next generation, forming a writhing mass – or mating ball. The female dies a few weeks after mating and laying her eggs, but the larvae pupate and become adults, staying underground until autumn, emerging to repeat the cycle.

September 10th-A brilliant day for birds continued….

As the tide began to return to the shore, every exposed rock in Penrhyn Bay was occupied by beady-eyed Cormorants.

Black-headed gulls also waited.

It seemed Rhos Point was the place to be for seabirds and waders today. In the time I have lived here I have never seen as many here all at once. I got there an hour or so before high tide, which is one of the best times to get close views of the birds waiting for their evening meal to be delivered. But as there were also such a large number of terns and gulls swimming on the sea’s surface and flying low over it, there must have been fish there drawing them in, perhaps a shoal of small fish, sprats or whitebait¹.

The tideline at Rhos Point was crowded with Herring Gulls, Black-headed gulls and Sandwich Terns. A woman arrived with two dogs and stood and watched as they chased along close to the water’s edge, sending many of the birds skywards. I will resist having a rant about that, but it troubles me that people think it’s OK to allow their dogs to do that.

Whilst waiting to see if the upped birds would return and re-settle I scanned along the sea edge to see what else might be waiting there. There were a whole host of Oystercatchers, trickier to see when their bright orange-red bills are tucked away whilst they rest. A few little Turnstones were dotted amongst them and then a larger bird at the back of this group, fast asleep with its head tucked well down – a duck for sure, maybe a female Red-breasted Merganser? Identifying ducks is not one of my strong points even when I have a good view of them.

Standing in the shallow water were a good number of Redshanks

and more Black-headed gulls.

A few Sandwich Terns were in amongst this group of Redshank, Turnstones & black-headed gulls.

I found only one Ringed Plover, although there could well have been more.

A large number of Sandwich Terns occupied a finger of exposed rocks with a few Oystercatchers and gulls, with many more gulls bobbing around on the surrounding sea.

The Sandwich Terns, here in large number today were noisy and excitable, with groups taking off and settling again in spots a few metres away along the shoreline. Some will remain here for the autumn and winter, but others will move on.

Their association with Black-headed Gulls is one I’ve seen many times.

There’s usually a crow or two waiting for the tide’s incoming feeding opportunities too.

Amongst the multitude of gulls swimming around were several Red-throated Divers – difficult to keep in sight as they dive frequently and disappear just as you think you may have one in focus, but a man close by with a brilliant telescope patiently located them and let me have a close-up look. Still not easy as you can’t predict where they’re going to pop up again, but I managed a couple of spots – what an exciting treat. At one point I thought I may have got lucky with a view of a group of six birds, also swimming and frequently diving and disappearing beneath the surface, but they turned out to be Razorbills, not quite as ‘special’, but still lovely to see.

They separated and mostly stayed too far out to see well without the aid of binoculars or a telescope, but as the tide progressed inwards, so also did one of the birds, allowing me a much better view of it.

As I watched the razorbill, the duck also took to the water.

I’m fairly confident it was a female Red-breasted Merganser. (The female Goosander looks similar but brown colour of head extends around neck leaving just a white chin). On this bird the white of the throat seems to extend down the front of the neck.

¹ Whitebait is a collective term for the immature fry of fish, typically between 25 and 50 millimetres long. Such young fish often travel together in schools along the coast, and move into estuaries and sometimes up rivers.

September 10th – Little Orme, Rhiwledyn Nature Reserve

Taking the old cliff path around to Angel Bay, I disturbed a beautiful fresh(ly) Painted Lady butterfly. It circuited round a bit before settling on a stony patch, pressing its wings tightly against small sun-warmed limestone rocks.

A small crowd of people gathered on the cliff edge above Angel Bay looked promising; maybe there was something exciting to see down there? But alas, no. They were simply chatting and the beach was empty. This convinced me that as I suspected, female seals don’t give birth to their pups here; if they did they would surely be here by now. There were seals here, but only two, both swimming lazily around in the water. On this cool, misty-damp morning I suspect it was warmer in the water than out. One was hanging in the water with just its face above the water, showing off a lovely set of whiskers.

Another was simply cruising around peacefully.

There is a thriving breeding population of Cormorants here on the Little Orme, so there is never a shortage of these brilliant birds to see, especially around their nesting site on the cliffs further around the headland. At this time of year and through the winter months, their numbers are boosted greatly and the steeply sloping cliff face that forms one side of Angel Bay is punctuated with a multitude of black dots and dashes. This is now Cormorant Central; the volume and frequency of arrivals and departures of birds rivalling that of aeroplanes into and out of a busy airport.

I wonder how they work out their perching places? Do early arrivals get the prime spots and do they now have their own patch, or is it up for grabs if they leave to fish for lunch? Do they stick to family or colony groups?

Whilst pondering on the whys and wherefores of Cormorant society, I was distracted by two little shapes down in the Bay – definitely birds but I was, of course, on the wrong side to see them properly. It’s not uncommon to get the occasional Guillemot or Razorbill here once the breeding season is over, so I didn’t really think further than that. Winter-plumaged Red-throated Divers didn’t enter my head at the time, but that is what they were. Birds we get around this coast during the autumn and winter, but most often much further out that you need powerful optical assistance to spot.

I must get back into the habit of taking binoculars out with me instead of relying on my camera’s zoom; sometimes it’s not enough. In this instance a glimpse and a snapshot was all I got anyway; these birds are for once aptly named as they do dive – a lot, reappearing nowhere near where they went under. I walked around to the other side of the rocky hump on the Penrhyn Bay side of the headland as from there you get good uninterrupted views of a wide expanse of sea. Birds fly low past here, keeping close in to the cliff, so some good views of whatever is travelling by; mostly Herring gulls and a few Black-headed gulls today.

Black-headed gull–Larus ridibundus

There was a Cormorant swimming around on the sea’s surface, giving a good view of the strong hooked beak.

A small black and white bird bobbed into view and this really was a Razorbill Alca torda. It was a good way out to sea, but close enough that I could see, through the camera lens, that it was in the process of changing from summer to winter plumage. The plumage of the throat and sides of the neck change from black to white in the winter – the side of this one’s head is still a mix of the two.

It was in no hurry to move away and intent on having a good grooming session.

Members of the Auk family, to which both Razorbills and Puffins belong, look a little like penguins, although they are not closely related. The next few images show some of the similarities between them; species of both have black-and-white colours, an upright posture and share some of their habits.

‘bye ‘bye little Razorbill, thank you for the photographs. Have a good winter.

Now a perfect example of how my mind skips around. Although tuned into ‘bird mode’, I spotted a wild cabbage plant and thought ‘maybe there’ll be a Large White butterfly’s caterpillar on those leaves’. And there was, so a gap in my last-but-one post can be filled in!

I was watching the Razorbill et al for a good half an hour, maybe more, then walked back around the cliff to have a last look around Angel Bay. The seals had gone, but the movement of a smallish bird on the cliff edge caught my eye. Rock Pipit came to mind, but no, it was a much lovelier Northern Wheatear. It was either waiting for the weather to improve or taking in some food before continuing on his long migration back to warmer climes; perhaps both.

Northern Wheatear – Oenanthe oenanthe

I’m not certain whether this was a male or female as when males are in their winter plumage both sexes appear similar. I’m edging towards male as there seems to be a slate-grey patch remaining at the top of the wing. The bird’s common name of ‘Wheatear’ has nothing to do with its food preferences or its ears, but refers to its white rump (i.e white a**e)!

More people arrived at the cliff edge and my bird flew away, down onto the big rocks on the beach.

I began heading in the general direction of the ‘way out’, but hearing a Stonechat nearby diverted to see if I could find it. They’re one of my favourite birds and are often obliging in terms of appearing in the open. I wasn’t disappointed; as I passed by one perched up on top of a bramble, within whose tangled depths a pair have regularly nested.

At first I thought this was an adult female , but as I got a closer look I could see it still has a speckled head, so it’s probably a juvenile of this year’s brood.

Robins were out singing all around the site today, but more wary now of being seen than when they sing in the spring. The one I finally got close enough to photograph was perched on a bracken frond keeping a beady eye out for movements on the ground below, ready to pounce.

Grey Seals on the rocks

In UK waters Grey Seals breed during the autumn. Although the entire breeding season spans approximately 8 weeks, individual females will spend 18-20 days ashore, during which time they each bear and suckle one pup. Towards the end of lactation they come into oestrus, as soon as 16 days after giving birth, and are mated.

August 28th

Another windy day on the headland of the Little Orme, but sunny too and the tide was out. Perfect conditions for seeing Grey Seals hauled out on the small pebbly beach of Angel Bay.

Angel Bay is an inlet on the Little Orme’s Headland on the North Wales Coast. Known locally as Angel Bay, on Ordnance Survey maps it is named in Welsh as Porth Dyniewaid.

Spotting one a short distance offshore in Penrhyn Bay was encouraging. The seal was suspended in the water with just it head above the surface facing towards the shore. They do this often and I’m sure they are ‘people watching’, as curious about us as we are about them.

There were boys in the bay, enjoying themselves greatly by jumping off rocks into the calm sea. I’m sure they were unaware of the seals not far away from them, hidden from their view as they were by an outcrop of rock . Unwilling to risk venturing ashore as they would normally have done, some were making the best of small islands of rock uncovered by the low tide, hauling out their bulky bodies to enjoy the warmth of the sun. Unfortunately there wasn’t room for all of them and some were left to drift around keeping a watchful eye out for a space to become available. Grey Seals are the largest breeding seals we have in the UK and those on view were definitely large, quite possibly pregnant females as they do congregate at traditional pupping sites in the autumn.

One had secured a rock of her own. She was rather beautiful, wearing a mantle of silvery grey velvet.

These three were more sociable and had left room for another.

After a bit of heaving and hauling the smaller one squeezed in, but there was no room left for more boarders.

There are nine seals in this picture – 6 on rocks and three swimming around hopefully.

The driver of one of the jet boats that take out sightseers from Llandudno pier spotted the seals and pulled in so people could have a closer look and take photographs of the seals. He must have passed the info on to other drivers as another boatload arrived a few minutes later. Then another who was a bit more intrusive and that I felt got a little too close. As I said before, seals are naturally curious themselves and are probably used to being observed from the clifftop, so they didn’t seem too bothered by the boats.

As the boat was leaving I took a short video as it is unusual to see the seals awake and moving, although they still weren’t doing much. Perhaps because they were rather put out about their lack of space the seals were quite vocal too, although most of the noise here was made by the departing boat & the wind!

An hour or so later the smaller rock had been taken over by a much larger seal; poor thing looks like she’s about to burst!
