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.

Keeping up with the Herring Gulls

January 9th – Chimney Pots, Rhos-on-Sea

After a few months of being relatively quiet and peaceful, our Herring gull neighbours are back and making their presence heard and seen throughout the village. Pairs stake out their territories early in the year and will defend them vigorously and vociferously from now until nesting begins, continuing to do so until this year’s offspring have grown and are mature enough to leave the site. It all looks and sounds like a lot of effort and hard work, but that is the price this pair are prepared to pay for a prime high-rise site.

These particular chimney pots are atop my daughter’s 3 storey house, offering well-elevated accommodation and boasting unrivalled 360° views extending over rooftops and the surrounding landscape, which includes the sea. It is a mere two-minute, maybe less, flight to the seashore. Both the male and female of the pair take responsibility for defending the site, sometimes together and sometimes on their own. They must need to take frequent breaks to restore their energy levels after a bout of meaningful squawking at the sky.

10: 29 – Female flies to roof edge, has a quick look around then takes off,

leaving the male in charge. I didn’t notice while I was taking these photographs, but he was not left entirely alone. To my amusement, a male Starling had his back. He has located his family home in the eaves of the adjoining property.

He seemed to have his work cut out, although from where I was standing in the garden I couldn’t see what or who he was directing his attention towards.

I couldn’t quite catch him in full squawk this morning, but he was making plenty of noise. He is still sporting his winter plumage and appears to be in pretty good shape, but he’s not a young bird. When I looked at my images I recognised him by his eyes, or rather by the lack of feathers around his eyes as the male of a pair I spent a lot of time watching back in the spring and summer of 2012.

As you can tell from the next couple of images he is looking a bit scrawny around the neck area, not as plump and well-filled out as he was back in the day.

Herring gulls breed for the first time at age 4 and a typical lifespan is 12 years. The oldest recorded Herring gull (from ringing records) was 32 years 9 months and 25 days old. This record was set in 2013.

10.39am – the female arrives back with a flourish and lends her voice to the warning-off aria.

he may be older, but clearly still has got what it takes to attract a mate and this one appears younger. It must be something to do with the status of his domain.

10.40 – She’s a bit on edge though and leaves again a minute later, I think she was chasing off another gull from their airspace, perhaps a rival female. It started to rain quite heavily then and he left shortly afterwards too.

Then and now

This is a head shot of the male showing his ‘scabby’ eyes taken this January

and below is one I took on July 24th 2012. He’s in his brighter summer/breeding plumage here, but had the ‘scabby’ eyes even then. It’s too much of a coincidence for it not to be the same bird isn’t it? He was considerably better-padded then too. If 2012 was his first year of breeding he would have been 4 plus the 5 years from then till now would make him 9, but I think he could be older.

This was him and his mate in full squawk back then, after they had successfully reared a chick that had fallen out of the chimneypot nest and landed on the flat roof below. More about that here: https://theresagreen.me/2013/06/20/theres-a-new-gull-on-the-roof

He was and I’m sure, still is a brilliant and attentive parent, bringing regular and diverse meals back to his hungry youngster. Including a starfish and regurgitated chips.

January 24th 2017

Back to the present. I was out taking my baby granddaughter for a walk along the prom and spotted this chap paddling for worms on the grass embankment. Old scabby eyes himself.

The Herring gull remains on the RED list of European threatened birds and it is illegal to harm them or damage or remove their eggs from nests.

Everyday Birds – The Blue Tit

Blue tit, Blue tits taking milk from bottles, folk names for Blue tit, melanism in Blue tit, Titw Tomos Las

Although blessed with visitors from a good range of species, Blue tits are without doubt the mainstay of my window birdwatching and have given me hours of viewing pleasure. There are few moments in the day when there are not at least one or two to see and at certain times there can be a good few more; counting them accurately is tricky, they’re too quick and mobile. I admit I hadn’t noticed any difference in the numbers of birds I’ve been seeing this year compared to previous years, so I was surprised to learn that according to BTO records, on a national scale there are significantly less of them this winter.

Throughout the UK Blue tits have always ranked amongst the most numerous of our garden feeder visitors, but last November (2016) BTO Garden BirdWatchers reported the lowest numbers of Blue Tits in gardens since 2003. They say:

” The explanation for our missing birds can be found by looking back to the early summer. The wet weather across the breeding season, particularly in June, would have made it difficult for the adults to feed themselves and their chicks. Normally we would expect to see large numbers of newly fledged young come into gardens to seek food, but this year BTO Garden BirdWatch results show the lowest numbers of Blue Tits in August for eight years. This indicates that fewer young birds survived than usual this year and these findings are supported by the preliminary results from the BTO Nest Record Scheme (NRS) and Constant Effort Sites Scheme (CES) which found that Blue Tits had their worst breeding season on record, thought to be due to a lack of young birds this year.”

All the more reason to appreciate these endearing little birds and continue to help them out where we can.

English name Blue tit Scientific name Cyanistes caeruleus (formerly Parus caeruleus), Linnaeus, 1758; Other names Eurasian Blue tit, European Blue tit Welsh Titw Tomos Las Conservation Status: UK: GREEN

Blue tits are tiny birds, measuring 12 cm (5″- 6″) long and weighing in at just 11 grams.

Blue tits are small. acrobatic birds with a gregarious nature, they have short legs and a sturdy bill which suits their omnivorous diet of mostly insects and spiders in the summer and a wide range of fruit and berries in autumn and winter.

The wings and tail feathers are bright blue and the back is olive-green. The underparts are yellow with a greyish-black stripe running down the belly which is usually narrow, but can vary. The cap, or crown, is a stunning bright blue. The face is a clean bright white accented by a narrow black stripe that runs through the eyes, there is a black chinstrap and a small black ‘bib’ under the bill. Males and females are the same, but males show brighter blue than females. Like all birds, Blue Tits can see ultra-violet light: the bright blue feathers on the front of their heads glows brightly under UV light and it is the quality of this feature that is thought to be the deciding factor in the females’ choice of partner.

It may seem to us that only a dozen or so Blue Tits use our garden feeding stations in the winter, but the truth is there could easily be many times this number passing through during the course of a single day. Blue Tits are largely sedentary in their habits, but studies of the local movements of British and Irish Blue Tits have shown that birds range over an area and move around in small flocks, or feeding parties, that often include other tit species, Goldcrest, Nuthatch, Treecreeper and even the occasional wintering Chiffchaff.

A Stranger Passing through

As one Blue tit looks pretty much like another, it’s almost impossible to tell who is who, so spotting through-visitors is tricky. But earlier this week I happened to spot an individual that looked ‘different’ to the ones I usually see.

Looking at him through the camera lens I could see he had an unusual dark patch of feathers above his beak and between his eyes and also a band of darker feathers around the top of the breast, giving it a slightly dirty appearance. This is the first Blue tit I have seen with darkened plumage, but the condition, known as melanism is apparently not that uncommon, although more common in the related Great tit. He didn’t stay for long as he was chased away by other Blue Tits. He must have stood out to them as looking ‘different’. (The BTO keep records of birds reported with abnormal plumage shown here.)

Acrobats

For the past couple of weeks I have been entertained by their acrobatic prowess as the small overhanging tree-of-unknown-species in front of my window has buds that are beginning to swell. This is their tree of choice in which to wait their turn for the birdfeeders down at ground level, to which they return to eat their snatched prize. Now they often have quick forage around the twiggy branches seeking out any lurking insects or larvae that may be hiding in them.

Blue tits are brilliant acrobats and can hang upside down from branches to search underneath them for insects. This agility and their light weight also enables them to search to the very tips of twigs.

The males are singing too – I photographed my first singer of this year on January 23rd.

Blue tits and us

The Blue tit and other tit species were long known as the Titmice, a name taken from Middle English (Icelandic) ttr = small, and mouse – in Old English mase=small bird. ‘Tit’ referred to any small object or creature and is of pre-7th century Norse origin. The first known use of ‘titmouse’ has been dated back to the 14th century and ‘Tom titmouse’ to around the 17th century. ‘Titmouse’ was used for this genus by most old authors, but Yarrell in his first edition shortened the name to ‘Tit’ and his example has been followed by many later authors.

The sheer number and variety of common and local variations of names bestowed upon them is a good indication that Blue tits have long featured in the lives of man. There is Blue Cap, Blue Bonnet (Shropshire & Scotland); Blue Ox-eye, Blue Spick (N Devon); Nun; Pedn-play, tree babbler (Cornwall); Pinchem (Bedfordshire); Tinnock, Yaup; Bee Bird (Hampshire); Willow Biter, Billy Biter (Midlands); Pickcheese (Norfolk); Tom Tit, Hickmall, Heckymal; Titmal (West Country.

Blue tits excel at problem-solving. Faced with intelligence test apparatus contrived by researchers, modern-day Blue tits have learnt to pull out a series of pegs or open matchbox ‘drawers’ to get at food. They have adapted readily to man and have been seizing opportunities to benefit from our lifestyles and habits for hundreds of years; sometimes this has worked out well for them but sometimes their opportunism has put them in harm’s way.

In the seminal account of English nature, The Natural History of Selbourne, which was first published in 1788, Gilbert White records his observations on the tactics local birds used to survive (or in some cases not) during harsh winters:-

“The blue titmouse, or nun, is a great frequenter of houses, and a general devourer. Beside insects, it is very fond of flesh; for it frequently picks bones on dung hills. It is a vast admirer of suet, and haunts butcher’s shops. When a boy, I have known twenty in a morning caught with snap mousetraps, baited with tallow or suet. It will also pick holes in apples left on the ground, and be well entertained with the seeds on the head of a sunflower. The blue, marsh and great titmice will, in very severe weather, carry away barley and oat straws from the sides of ricks.”

Friend or foe?

It’s hard to imagine that Blue tits have not always been regarded with fondness and affection by everyone and were actually once thought of as ‘foes’ by many gardeners with fruit orchards. The following is an extract from one of my favourite old nature books, which according to the inscription in the front was given as a birthday gift in 1923. The chapter is entitled ” Attracting Wild Birds to Gardens” and written by Oliver G.Pike FZS, FRPS who was clearly already spotting the signs that our wildlife was in need of our support.

“I have watched the Blue Tit and its mate busy on one of my apple trees in the month of April; they were carefully searching the branches for buds which contained insects, and these were quickly destroyed – that is, both bud and insect. They seemed to be doing a lot of harm, but I allowed them to continue, and later on in the year that same tree had a fine crop of excellent apples. So many gardeners see a bird destroying buds and immediately jump to the conclusion that it is a pest and ought to be destroyed. I knew one gardener who in the course of one season trapped and destroyed over fifty Blue Tits. He quite overlooked the fact that by doing this he was allowing for the increase of 100s of 1,000s of insects which would do far more harm to the crops. One pair of Blue Tits which succeed in bringing up their family of, say ten young, will during the period of feeding them account for not less than 10,000 insects, the majority of which are very injurious to many garden crops and flowers, and every one of these will be captured within 100 yards of the nest.”

The successful breeding of chicks is dependent on sufficient supply of green caterpillars as well as satisfactory weather. Breeding seasons may be affected badly if the weather is cold and wet between May and July, particularly if this coincides with the emergence of the caterpillars on which the nestlings are fed.

Infamous behaviour

But Blue tits are perhaps most well known, amongst our older generations at least, for raiding milk bottles. It was first noticed in Southampton in the late 1920s that the local Blue tits had somehow learnt to remove the caps of milk bottles that had been delivered by the milkman each morning. The birds pierced and tore the lid, sometimes removing it completely, then helped themselves to the rich cream that had floated to the top.

Even though blue tits rarely travel farther than a few kilometres from where they’re born, they learned this behaviour from each other by watching their neighbours. Thus, by 1935, the Blue tits living in London were regularly stealing cream, too. The behaviour soon radiated outwards and became familiar nationwide to anyone that had milk delivered to their doorsteps. I’m sure if the delivery service was still available, the cheeky little birds would be helping themselves to this day, they certainly were still taking mine back in the late 1990s/early 2000s. It had to be milk with cream that rose to the top of the bottle though; they can’t digest milk, so the skimmed stuff is no good!

The Redwing

Coch Dan-aden, grey squirrel, redwing, Turdus ileacus

For a few magical days earlier this month I enjoyed the privilege of close sightings of Redwings as they travelled around our local woodland foraging for food. Special sightings indeed, and better still I didn’t even need to leave my flat: all but one of the following photographs were taken from my kitchen window.

December 31st 2016

09:10 Thrilled to see Redwings this morning – several flew through the cover of the trees and shrubbery behind the building, with one pausing briefly in view of the kitchen window. There was a flurry of bird activity around that time; they were preceded by a mixed group of small birds, including Long-tailed, Great & Blue tits and seemed to have a variety of blackbirds travelling with them, so may have been a thrush feeding party following a tit feeding. The light was poor and I only managed to get one not-so-good photograph, but at least it is a record of the sighting.

English name: Redwing Scientific name: Turdus ileacus Welsh: Coch Dan-aden Status in the UK: RED Redwings are red-listed in the UK as although the majority are autumn-winter residents, we have a very small breeding population, restricted in range to the northern third of Scotland.

Other local names: Swinepipe, Wind Thrush Scientific name from: Latin: turdus=a thrush and Latin: iliacus=of the flanks (from ile=flank)

Redwings are Autumn-Winter residents of the UK and the smallest and daintiest of our thrushes. Smaller than the Song thrush, they are often shy, but a close view reveals a prominent whitish supercilium (eye stripe), warm rust red patches on the flanks and under the wings and cool grey-brown upperparts. Males and females are alike.

January 2nd

This was the day of my encounter with the flock during my walk in the woods, already described in the previous post. There were blackbirds with them then too and I went on to see the mixed small-bird feeding party just minutes later.

The Redwing’s diet is mainly composed of invertebrates, supplemented with berries in autumn and winter. Wintering Redwings may be seen together with Fieldfares foraging in open fields, but they also feed with other thrushes in grassy paddocks or in woodland. Visits to gardens may be brief and are usually prompted by harsh weather.

January 5th

A frost last night left the ground hard and sparkling white this morning, and it remained cold for much of the day despite the bright sunshine. The hard ground may have driven the Redwings to seek easier food sources. This was brilliant for me as from early morning a small flock of them arrived intermittently throughout the day to pick at ripening ivy berries. So once again from my window I had a succession of fairly close-up views of them, although most of the time they were at least partially hidden behind tree twigs or within ivy foliage.

The majority of Redwings arrive into the UK during September and October as birds cross the North Sea from Scandinavia and Russia. Those arriving into Wales and other western areas are most probably Icelandic birds. Redwings are night-time migrants, and if you are lucky and listen out on dark clear autumn and early winter nights, particularly in the east of the country, you may hear the thin ‘tseep‘ of a flock overhead. As winter arrives Redwings will have largely finished their journeys, settling in the warmer and relatively frost-free areas away from the east coast. They stay with us till March, although hard weather may force them to migrate further, with Scandinavian/Russian birds (the iliacus race) continuing westwards to Ireland or southwards into southern Europe.

Taking a few minutes to rest in the warm sunshine:

“Any attempt to estimate the size of the wintering population of Redwings in Britain and Ireland meets with the same problem as for the Fieldfare: the numbers vary from year to year, and also in the course of a single winter, and major shifts of population may take place in response to weather and feeding conditions. “

( David Snow 1987 – The Atlas of Wintering Birds in Britain and Ireland, edited by Peter Lack)

Another interesting observation I made today was of a Grey squirrel that seemed to be ‘guarding’ the ivy berries. I watched it chase away another squirrel several times, but also noticed it was chasing the Redwings away too, charging at them by running along branches towards them at speed, tail all fluffed out!

January 6th

Milder temperatures may have allowed the Redwings to move on in their constant search for food and today I saw just one bird from my window. It wasn’t in the usual hurry and lingered for a few moments, not moving far and presenting itself to me from various angles so I got some lovely views of different aspects of its plumage and general ‘giz’. They really are beautiful birds.

I saved the best for last.

Wintergreens and Birds in the Woods

January 2nd – Bryn Euryn

Clear blue skies and frosted grass sparkling in brilliant sunshine were too much to resist, this had to be the perfect day for my first long walk of the New Year. Less than five minutes along my path into the woods I knew this was set to be a slow walk when I stopped to photograph berries on a holly tree. I was surprised to find so many remaining uneaten and noted ripe ones fallen and peppering the ground beneath. If not for that I may well have missed the flock of beautiful redwings that burst from the trees on the steep lower slope of the Bryn, exploding from their cover and rapidly scattering like shot from a gun, targeting branches of trees close by. There were a number of them, but impossible to count as once landed they are really difficult to spot. I was thrilled to see them and to be able to watch them and delighted that I got any photographs at all, so of two, this was the best.

Redwing – Turdus iliacus

I knew there were redwings around as I’d been fortunate enough to see some from my kitchen window on the morning of New Year’s Eve and one a couple of days before that, but I had no idea whether they were just passing through or were here to stay. I’m not certain, but I think they were searching through ivy for ripe berries. Now I am hopeful they will stay for a while, at least while they are finding food.

Ivy berries are in varying stages of ripeness

Polypody fern

The majority of deciduous trees are bare now, but there is much that is green. Here we have our native holly, copious amounts of ivy, yew, a few Scots pines that are a native but that were most probably introduced, and rather a lot of laurel, once much beloved by Victorian gardeners.

At ground level there are ferns, the polypody in the photograph above, and also hart’s tongue and male ferns.

Hart’s tongue & a small male fern

And there’s lots of moss.

Then my reward for wandering slowly and numb fingers on my gloveless right hand, left free to focus and press the shutter button on the camera; suddenly I was surrounded by the joyous energy and excited sounds of a number of small birds. A feeding party, a collective of a variety of species of small woodland birds united in the eternal search for food.

It’s impossible to say who arrived first, I didn’t sense that there were leaders and followers, more that the flock was operating as a single entity arriving at a pre-determined spot with potential for all members. Of course there were blue tits, also great tits and a couple of coal tits.

Blue tit

An encounter with a feeding party of birds is a magical, uplifting and energising experience. The birds themselves exude excitement and energy, seeming to delight in the thrill of being part of a gang.

Coal tit

The enchanting long-tailed tits were there too.

Long-tailed tit

Once arrived they quickly settled to foraging amongst the trees and shrubbery, splitting back into their families or species groups. I would have been happy with the company of just the exuberant tits, but have to admit my attention was stolen from them when I noticed the treecreepers. Often included as members of a feeding party, there were two on a tree in front of me and then another two, closer to the side. What a treat to have that many of these gorgeous little birds so close and not only in range of the camera but with the added bonus of bright sunlight too.

Treecreeper

I lost track of time watching the birds, but they gradually moved away and passing people walking a dog and chatting broke the spell and I too turned to continue my walk. But there was one more little treat to come – two tiny goldcrests, that may or may not have been with the feeding party, were working their way through a small holly bush nearby. I watched them for a good while, but they eluded capture by my camera, they are much too quick especially when trying to contend with foreground vegetation. The shot below was the best one I got!

Goldcrest

Before heading on to the trail around the Bryn I had a look at the view over the boundary fence. The higher peaks of the Carneddau mountains have snow with clouds above them that look to be holding more. The warming sunshine had them shrouded in a light veil of mist, with more rising from the Conwy river in the valley below.

Waders v Weather

Curlew, great black-backed gull, Oystercatcher, redshank, Turnstone, turnstone flock

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.

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.

A Secluded Spot for Sunbathers

“The perfect spot for sunbathing, in a peaceful woodland edge location, offers privacy and safety in which to relax or indulge in some leisurely grooming preening. No charge for use of facilities”.

This summer this ideal location, set conveniently for me just a few metres from my kitchen and bedroom windows, has been a popular spot with some of the local birds, particularly some of the younger ones.They come to make the most of this sheltered sun-trap to sunbathe, also known as ‘sunning’ in application to birds. Sunning birds may become so absorbed in the activity that they are easily approached, which can make them vulnerable to predators. They are safer here; there is no easy access to this spot from any angle, although a savvy Sparrowhawk may possibly be able to make a strike if it got its timing right so as not to cast a shadow.

Dunnock and Blackbird sunning together

Most commonly we see Blackbirds and sometimes Robins sunning in gardens , but other species indulge too in slightly different ways.

Sunbathing Blackbirds are a fairly common sight in parks and gardens

To begin sunning, birds orient themselves to expose the maximum amount of their plumage to the sun. The classic sunning posture is thus: head and body feathers are fluffed up and out and depending on available space and/or sense of security felt, one or both wings are held out from the body with feathers spread; the tail is sometimes fanned out too. The bird may keep the same position throughout a sunning session, or it may change positions to expose different parts of its body to the sun.

Sunning is often a precursor to preening, vital to a bird’s feather maintenance, and in this instance it is thought this has two effects; one is that the sun’s heat helps to spread preening oil across the feathers. The other is that it drives out parasites from within the plumage that can then be more easily dislodged as the bird preens.

Sunning and Preening demonstrated by a Dunnock

I’m fairly sure this session was more concerned with pest control than anything else.

Firstly, adopt the sunning pose: fluff out feathers and spread tail and wing feathers. Well, alright just the tail feathers will do for now.

Secondly, begin preening with any particularly itchy spots caused by unwelcome hitchhikers.

Pay attention to armpits

Some areas such as the head and around the eyes and bill can only be serviced by extending and lifting the leg and having a good old scratch.

It helps to have a flexible neck.

That will have to do for now, it’s getting a bit shady here.Time to go.

The young Robin in the following sequence of images seems to be similarly afflicted with ‘lumps’ apparent on its neck.

The head and neck are areas birds are unable to reach with their bills and have to scratch with a foot.

The other side needs attention too.

It looks as though the bird’s frantic scratching has created a bald spot. And is that another lump under its eye?

During sunning sessions birds often have their bills open. This is because the warmth of the sun raises their body temperature and as they can’t release heat by perspiration, they have to regulate it some other way, so will gape and sometimes pant in order to lose heat.

To sum up, no-one knows for certain the reasons birds sunbathe, although several theories have been proposed.

To maintain the bird’s feathers in good condition. Exactly how sunning assists with this is not known, despite being widely studied. All birds have a gland on the rump, called an oil gland. The ‘preen-oil’ that this gland produces helps to keep the feathers flexible and hygienic. As preening usually occurs directly after sunning, it has been suggested that the sun affects the preen-oil in the feathers in some beneficial manner, or that it helps to synthesize the Vitamin D and helping to regulate it’s temperature.
The heat from the sun may stimulate activity in parasites within the feathers, making them more accessible when the bird starts to preen.
Birds also make use of the sun’s heat to increase their body temperature or prevent heat loss. This form of ‘sunning’ is also used when the bird dries itself after bathing.
They do it simply because they enjoy it.

I was pleased to see House sparrows once again topped this year’s list of the RSPB Big Garden Bird Watch in England, Wales and Scotland, but we shouldn’t get complacent, they’re still on the ‘Red List’ of birds requiring the highest conservation priority, along with other species needing urgent action.

Over the past couple of weeks I have spent some afternoons dog-sitting for my daughter, which has given me the opportunity to catch up with the little flock that regard her garden, together with those of the immediate neighbours’ as their territory.

House sparrows love to bathe and sit on the fence to dry out

I don’t blame them for settling here, they have everything they need to live as easy and productive life as it is possible for birds to enjoy. Throughout the year they come and go throughout the day, enjoying the bounty of well-stocked bird feeders, a pond in which to bathe and hedges to provide cover and perching places. Every evening the whole community returns to roost safely within the prickly pyracantha hedge. Now they are well into the throws of nesting. Earlier on they began refurbishing last year’s nests or rebuilding any lost through winter pruning. There are perhaps 4-5 nests, sited close together, although the level of noise that emanates from within sounds like there should be more. A couple more pairs prefer the loftier location of the eaves above the third floor at the front of the house.

In the breeding season the dominant birds leave the safety of the hedges and perch prominently on the highest points of shrubs to proclaim their territory, although the individual territory of the male House Sparrow really only consists of the nesting hole and a very small area around it, which is defended vigorously.

Dominant males have larger, darker feather ‘bib’ patches

Females judge males on the vigor of his behaviour and also by his plumage. The black bib and how it is displayed is hugely important for him and size matters. Apparently males with small bibs can be induced to behave more boldly if they have bigger and blacker bibs painted on them!

Every year, when the nests are built or refurbished, the sparrows systematically strip the soft fluffy seed heads of the pampas grass that grows in a neighbouring garden. I spent ages one afternoon watching them as they returned repeatedly to strip the stems and carry off the fronds. I assume they use the fluffy parts to line their nests, but wonder if there are seeds to eat too? I find this behaviour fascinating and have witnessed it in South Wales where pampas was growing and also in our garden in Spain. In each location they begin working on the plant on the same day, arriving sometimes in numbers, males and females and set to, detaching the fronds and carrying them off a beakful at time. The harvest continues over a few days until the stems are left bare.

A Starling pair are nesting in one of the chimney pots and they too enjoy the feeding and bathing facilities, also pausing to dry out on perched on the fence or at the top of the hedge. Still one of our commonest garden birds, its decline elsewhere makes it too a Red List species.

The bird in the photographs below is the male of the pair, identified by the blue colouration at the base of his bill; the female has a similar patch that is coloured pink.

The male sings beautifully, sometimes from up on the roof but also from the fence and the top of the hedge. His mate doesn’t get out much at the moment, so must be sitting on eggs.

The starling was singing, hence the fluffed out throat feathers

PS: The pampas grass is now just a collection of bare dry stems!
