Several months and a whole season have come and gone since I posted anything on this blog. It’s been a sad time for me and all of my family as my beloved Dad reached the end of a very long life last September. He was the one that noticed and encouraged my early interests in the nature around us and taught me the names of common wildflowers, butterflies and most particularly birds. He didn’t claim to know everything, but more importantly he gave me the gift of noticing what was there and the encouragement to find information I wanted for myself. He never really got the concept of blogs, or indeed anything to do with computers, but was always interested to hear what I had seen and where I’d been, particularly about the places here in North Wales that he took my sisters and me to spend time in when we were young. Some of those places have remained very special to me and I’m sure that when I visit them, that’s where I’ll always find him.

______________________________________________________________________________

Thank you all for your patience and sticking with me and thank you to new readers that have signed up who must be wondering where I’d disappeared to. While Dad was ill I was spending a lot of time down in my old haunts in Northamptonshire, where my sisters still live, and it was reassuringly familiar and not too greatly changed in the decades I’ve been away. I may do a post or two about our walks there if I am unable to come up with anything more current, but for the time being the so-far mild winter is giving me plenty of opportunity to get out and ideas for posts, starting with this one about the  wading birds that are about now on our local rocky seashore.

2nd January 2104 

A brilliantly sunny day winkled me out of my cosy shell this morning and I set off, camera to hand to see what I could see from the promenade. I realised I had lost track of the ebb and flow of the tides and had no idea of its current state, so was initially quite disappointed to see that it was fully in and very high. That meant there would be no waders to be seen picking their ways through the rocks that strew the shoreline of Rhos Point pecking and probing the muddy sand in search of food. But I’d made the effort to get myself out and I wasn’t about to go home with nothing, so I thought I’d at least walk for a way for some much-needed exercise and if nothing else there may be a Rock Pipit or two on the rocks or the sea wall. The sea was as blue as the sky and ruffled by what I was feeling as a bitingly cold breeze. I hadn’t walked far when I noticed a largish bird swimming around on the water, meandering randomly and frequently diving and disappearing under the surface for minutes at a time.

Needless to say, I hadn’t picked up my binoculars and couldn’t properly see what I was looking at, even with the assistance of the camera lens, but from its general ‘giz’, and the fact I’ve seen them here in previous years, I decided it was most likely a Great Crested Grebe. It wasn’t alone either, although individuals were spread quite widely apart, at one time I counted ten of them. I could not get a decent image of any one of them though, so this one is a token effort to verify the sighting! 

” In winter, Great Crested Grebes show a marked shift from inland waters to the sea, although on the continent large numbers remain on inland lakes, e.g. in Switzerland (Cramp 1977). In normal winters, Britain and Ireland receive birds from continental western Europe. During severe winter weather, birds move through Britain in search of milder conditions either to the west in Ireland, or southwards to France (Lack 1986).” http://jncc.defra.gov.uk/pdf/UKSPA/UKSPA-A6-4B.pdf

I walked quite a distance towards Penrhyn Bay, stopping now and then to try to get a better image of a Grebe. I spotted one a little further in and got a slightly better view from the top of a set of steps that lead down to the beach. You get an idea of how far the water reaches regularly as the bottom treads are worn smooth by the repetitive scouring of salty waves climbing them and retreating with some force.

I wasn’t enjoying walking into the cold wind so I turned around and walked back, but carrying on towards the village. Just past the tiny St. Trillo’s Chapel I caught a glimpse of a bird flying down on to the big rocks below the promenade; a Turnstone. It landed out of eyesight, hidden amongst the huge boulders, but as I searched for it, up it popped onto a rock very close by.

Turnstones are common winter visitors to all our British coasts and gather in the greatest numbers on rocky and stony beaches, as here in Rhos-on-Sea. I was very happy to see it, as they are perhaps my favourite small wading bird, and because they are rarely alone I was confident there would be more to see.

In previous years I have seen small groups of mixed species of  waders on the rocks here, so I was hopeful there would be more to see. I didn’t have to go far before spotting another little group waiting for the tide to turn and leave their lunch, this time Ringed Plover and Dunlin.

Ringed Plovers are amongst the most common of our shore birds, although the increase in building in seaside localities and our intrusion onto beaches that were once remote, where they traditionally used to breed, have taken their toll on populations.

Dunlin are amongst the smallest of our shore birds. Some are present in Britain all year round, and as with Curlews, they winter on coasts and breed mainly on upland moors. Numbers are swelled when sizeable flocks come for the winter.

Dunlin were known to wildfowlers of old by a diverse variety of names, including ox-bird, ploverspage, sea snipe and stint.

As I watched them I had to wonder how these birds know when the tide is about to turn? It’s definitely not just a lucky guess! When I first began to watch them they were all quite still and quiet, but then in a heartbeat something changed and they became suddenly more animated. Up till that moment they had ignored the close proximity of people walking and me pointing a camera at them, but now people passing by with a dog or cyclists triggered off the Dunlin and Plovers and theytook off as one in a tight little flock out over the sea towards the harbour breakwater, then looped back, showering down to land a few feet further along the rocks. The Turnstones woke up too and were the first to venture nearer to the water, ready to get down onto the first uncovered patches of sand.

As the tide’s turning became more imminent, Oystercatchers began to arrive. They too had been waiting, but a bit further away on top of the harbour breakwater alongside the herring gulls.

Most of the Oystercatchers headed straight out to the far end of the Point, but a few chose to join the Turnstones, Dunlins and Plovers. Oystercatchers are the most numerous and conspicuous of the waders here and are a familiar sight on the mussel beds, on the rocky shorelines and in small groups flying low across the sea. They are noisy and gregarious and wonderful, but usually some distance away, so it was lovely to get this opportunity to see them more closely for a while.

The shrill calls of the Oystercatchers often ring out from where they spend most of their time feeding or as they fly, but I hadn’t realised they also use it to greet other birds. I watched and listened, fascinated, as a pair performed a little greeting ritual in front of me.

Their performance reminded me of the Herring Gull pair that raised their family on our roof last year and involved ‘bowing’ to one another, beaks open and pointed towards the ground whilst emitting their shrill call, rather ear-piercing at this distance. I am assuming they were a mating pair, and that is something else that is mind boggling; how on earth do they recognise one another in a crowd?

The magical moment arrived when the sea had retreated just enough to expose small patches of the seabed. The larger Oystercatchers were first in, followed closely by the Turnstones, then the smaller Dunlin and Ringed Plovers, once they were confident they wouldn’t be caught out by a rogue returning wave with nowhere to run to.

The tide comes in and goes out quickly and by the time I turned to walk back much of the rocky shore of the Point was revealed and already heavily sprinkled with Oystercatchers.

I hadn’t noticed any Curlew fly in, but hearing one I looked more closely and caught sight of one that had just picked up something to eat, very closely observed by a couple of Oystercatchers, who are certainly not averse to stealing should another take its eye off its prize.

Turnstones

The tide was high this morning when I arrived at the promenade, so I was not expecting to see many birds about foraging on the shore, but I’m happy enough to just watch the sea, so I looked out over the railings anyway . I’m glad I did that, as there beneath me, a whole flock of Turnstones were perched atop the sea-defence boulders immediately below. The birds were either resting quietly or catching up on their preening as they waited for the tide to turn and expose the rock shore once more.

11/9/11- Turnstone dozing

Turnstone-Arenaria interpres

Turnstones are distinctive medium-sized waders. They are high Arctic breeders, and are migratory. They are chunky powerful birds that have strong necks and bills that are well suited to their feeding technique. As the name implies, these species readily turn stones, shells or seaweed looking for hidden invertebrates. They eat insects, crustaceans and molluscs.

11/9/11-Members of the flock were resting or preening their feathers

As the birds were obligingly still, I counted 70 birds in varying sized groups spread along a length of the rocks, but there may have been more below and out of my sight.

11/9/11-The birds' rest was temporarily disturbed by a splashing wave

It would be interesting to know where the birds have come from as these particular birds have not been here for long. Turnstones are present around our coastline for most of the year. Birds from Northern Europe pass through in July and August and again spring, then Canadian and Greenland birds arrive in August and September and remain until April and May. Non-breeding birds may stay through the summer.

11/9/11-Plumage is mottled shades of brown, black, grey and chestnut brown. The head is patterned either brown and white or black and white. Underparts are white. Legs are orange.

Turnstones spend most of their time foraging creeping and fluttering over rocks, picking out food from under stones.

Their appearance is striking in flight, with white patches on the back, wings and tail.

Where to see them

Turnstones are found all around the UK coastline. They are strictly coastal,and are seen on stony, sandy and muddy shores beaches and are often found together with other waders such as Purple Sandpipers. The birds particularly like feeding on rocks covered with seaweed, and will feed along seawalls and jetties.

Oystercatchers, and more on the seashore

28 April

I was leaving sunny Rhos-on-Sea to start heading back to rainy Spain this evening (with a few days in London first), so a last walk along the promenade and seashore was a must this morning. It was a good day to leave on, the morning was bright sunny and warmish, cooled by a bit of a breeze that made for a pleasant temperature for walking.

My first stop was at the rocky breakwater, where I was hoping there may be some birds foraging, but there were only Herring Gulls. As I was about to move on though I heard the familiar ‘tschissick’ call of a Pied Wagtail and one duly arrived, landing just a couple of metres away from me. I’d had a couple of previous sightings of the birds, around the golf course area and a male ‘singing’ from a rooftop, but this was a perfect view of a female. The male bird is all black above and has sooty-grey flanks; female is dark grey on mantle/back but has black crown, rump and uppertail-coverts. Slightly different in appearance to the race of Motacilla alba we see in Spain and the rest of Europe, this is Motacilla alba yarrellii that occurs in Britain and Ireland and locally on adjacent Continental coasts.

The tide was on its way out exposing a narrow strip of pebble beach, so I walked down to it via a concrete ramp to see if anything interesting may have been left by the receding sea. On the walls of the ramp, nicely warmed by the sun I noticed several little insect-things scuttling about, which on closer inspection turned out to be Bristletails – of the 3-Pronged variety.

3-pronged Bristletail – Petrobius maritimus

The insects belong to a primitive group of wingless insects (Apterygota) that are dependent on humid conditions. The 3-Pronged Bristletails belong to a small order ( Thysanura), all the members of which have 3 ‘tails’, comprising 2 cerci and a central projection known as the epiproct. The most familiar member of the group is the Silverfish. I am open to correction on this, but from my research and based on their location I am assuming the ones I saw to bePetrobius maritimus:

Description: A slender brown insect, up to 15mm long, with antennae that are almost as long as the body. Central ‘tail’ distinctly longer than the 2 side tails. Habitat: Close to high watermark on rocky coasts and short distance inland in crevices. Status and distribution: Common and locally common throughout in suitable habitats.

I’ve seen very similar-looking  insects to this on our covered terrace walls in Spain, but we are a  kilometre or so  inland from the sea, so perhaps we were closer once upon a time and they got marooned and have adapted. I must try to find one and compare them.

Reaching the beach I disturbed a group of Herring Gulls that had been foraging on the sea edge. They flew up and began circling around, voicing their objection loudly and their proximity gave me a moment of anxiety as I visualised a scene from Alfred Hitchcock’s ‘The Birds’. Then it occurred to me that they may have been alarmed by my long camera lens, so if they thought it may be a gun I was quite safe from attack. Phew.

I was soon distracted by birds I had been hoping to see, a number of Oystercatchers, very handsome in their immaculate black and white plumage, were standing on rocks at the sea edge looking down at the receding water and anything edible it may be leaving behind.

I became absorbed by the sight and was enjoying my close-up views of the birds, so the arrival of  a man with his dog startled me. He  stopped to chat to me and I told him I was watching the Oystercatchers – the camera with a big lens may have given him a clue I was taking photographs too, but he carried on walking straight towards them anyway. Needless to say they all took off to look for somewhere more peaceful.

The expansive mussel beds located here attract large numbers of Oystercatchers, although they also feed on cockles, limpets, small crabs, shrimps and worms. Breeding takes place after the wintering flocks have broken up, in mid-April in the south and May or June further north.

I turned to retrace my steps up to the promenade, almost stepping on this huge stranded lump of a jellyfish.
