Whoopee at Cliffe!

2 Curlew Sandpipers in breeding plumage, 2 Bar-tailed Godwits, 11 Dunlin, 13 Ringed Plover, 2 Grey Plover, 700+ Avocets, 100+ Great Black-backed Gulls, 70+ Black-headed Gulls, 3+ Common Gulls, Larus canus, 4 Common Tern, 1 Green Sandpiper, 4 adult and 9 young Shelduck, 20+ Pochard, Tufted Duck, Mallard, 1 male Ruddy Duck, 20+ Redshank, 10+ Greenshank.

The Curlew Sandpipers, Calidris ferruginea, were absolutely fantastic. The most obvious feature was the patchy rusty red chests, against a white background as the wind fluttered the feathers.The next feature seen was the dark eyestripe against the whitish background of the face - the white being the clear pale supercilium above the eye, and the whitish area of the cheek below the darker eyestripe. The back was grey-brown in comparison, and I thought I saw the scalloping type pattern. The birds were not there very long, and when they flew I looked carefully for a wing bar, which I did clearly see, about the same visibility as a Dunlin. I thought I also caught the whitish rump above the darker tail tip, bit I must admit I was concentrating on the wings and should have looked at the rump as well. Overall the bird was slender and stylish, and I compared it in my mind to Audrey Hepburn! When I described what I had seen to a very nice chap scoping the birds a bit further up, he named it as Curlew Sandpiper (we agreed that a Knot was significantly larger and chunkier, with a much shorter bill). When I checked BWP it seemed to fit. It was when I checked the images on the internet and the Collins Guide that I was convinced the ID was correct.

This is one of the Black-headed Gulls in flight, showing the dark underwing:


And here is one of the two or three Common gulls I saw in with the other Black-headed Gulls I saw roosting at the estuary end of Flamingo Pool:


This is the one Greenshank up this end of the reserve. Talk about Audrey Hepburn again!


This is a Little Egret and two Dunlins.


As today's new acquaintance drove off from the barrier at the Meadwall, I caught sight of a smallish wader zigzagging towards me low along the ditch to the right of the track. Very black and some white in appearance. My first impression was actually of a dark hirundine with stiffer wings (the RSPB website says it resembles a House Martin in flight). The old PDH field guide refers to rapid flight with jerky snipe-like wingbeats. It settled and vanished so I got the telescope set up. To my astonishment I quickly got on to it, and saw a sandpiper very dark on top and very pale underneath, not small. The throat and chest were dark (no "white peak" between the wing and throat), and I thought "sandpiper" in general appearance but it wasn't bobbing (although Green Sandpipers do bob) and looked too dark above to be a Common Sandpiper.

Later as Monty put it up again I heard a twit-twit-twit (characteristic three note whistly tone) call and saw a bright white rump - it was a Green Sandpiper, Tringa ochropus! This looked just like the bird I saw about 18 months ago on a nearby ditch and the two I saw nearby two autumns ago but misidentified originally, and I was really happy to feel that the mystery has now been completely solved in my head, with a rather excellent view today. The call was great confirmation and a low zig-zagging flight is also a characteristic of the bird's behaviour. The best estimate of the known UK winter population is about 900 birds, together with an occasional breeding pair, but this seems to be a fairly reliable site for them.

The Ruddy Duck on Black Barn Pool 2 was an incredible sight.with a blue bill that looked as if it had just come out of a Dulux Gloss colour catalogue. The bright white face, black cap and rufous body with a long perky tail were like a vision of colour. I only saw the bird for a moment and did not rediscover it despite searching for where it should have been.
