And here a comparison with a Great Black-backed Gull. It's a big gull - what a cracker!
Yellow-legged Gull, Calvert Lakes, Buckinghamshire with argentatus Herring Gull behind. Notice how the poor lighting conditions makes these birds look dark.
Possible Caspian Gull at Calvert Lakes. It slept virtually the whole time I was there except on one occasion when it sat up in the water and looked like a Casp. Never got a look at the primaries though....
Yellow-legged Gull, Albert Village Lake. This one took half an hour of tracking before it showed off its bright yellow legs and P10/5 formula. There were lots of smartish looking argies on AV and Calvert lakes and I found it very hard going and sometimes frustrating trying to ID these birds. I disregarded any bird where I didn't see leg colour and primaries.
A nice comparison with Yellow-legged Gull, centre with argenteus Herring Gull (right) and argentatus Herring Gull (far right). The argy looks at least as dark as the YLG in this image but despite advanced moult into new plumage it still manages to look slightly scruffier.
Second winter Yellow-legged Gull, Albert Village Lake.
Possible Caspian Gull at AVL. Another birder who seemed to know what he was doing saw the primaries on this bird (and ID'd it as a Casp) - I didn't. In this image the bill looks chunky and bright. In one very poor image I have the underside of P10 is partially shown and seems to have extensive black more in-line with YLG.
"Hooded" Lesser Black-backed Gull on AVL.
Albert Village Lake - very civilised place to watch gulls with proper footpaths and good views!
Mute Swan JP4 back on Rixton pools. I have been following this swan for over a year now and it's good to see him back at Rixton. Two ringed swans on HGF originated from Leigh and Farnworth.
Lesser Redpoll at Moore. This bird was with a flock of Goldfinches - not much else about on a very foggy day.

No birding of note last weekend. A foggy morning stroll around Moore was about it and I can't be bothered to trawl through the birds I did see.

HGF remains pretty much the same and completely frozen again this morning.

Around 80 Tree Sparrows are consistently at the feeding station. In the garden a small tabby cat which appears to have adopted us keeps haing a go at the Pheasant. The said bird just looks at her in disdain before kicking out and making the cat go away. Comedy value!

Been working away this week - this enabled me to get in a couple of gulling sessions.
xxxxx
First one was at Albert Village Lake. There are probably only around 1500 large gulls on this lake but lots of variety and interesting stuff. The third winter Glauc is a superb bird and stands out a mile. The rest is rather more complicated. Several birders there reported two Caspian Gulls - having seen one of them I remain to be convinced and I'm not that good at gulls. It's also very hard picking out the YLG's as there were lots of bright looking argentatus Herring Gulls to fool me and some of the YLG's I did see did not have the classic looking structure - particularly the small ones (females?).

I did pick out 6 YLG's (5 adults and the second winter) and later I headed over to Foremark Reservoir for dusk where I picked out possibly the same 3cy YLG and also the Glauc.

The following day I spent some time after work at Calvert Lakes. These are two lakes split by a road, one of which is a nature reserve and one is a sailing lake. There were around 8000 gulls on the latter and not viewable (until I figure out how the locals get on). On the nature reserve were around 1000 large gulls and absolutley no BHG's. I picked out 2 YLG's but I wasn't patient enough to keep tracking these until they showed their legs and primaries. There was a possible Caspian Gull, however I didn't get a chance to see its wing configuration. Also here was a Black-necked Grebe and two low-flying Red Kites providing an aerobatic spectacle. Typically just after I had put my camera away, a Muntjac walked right across the front of the hide....

At the beginning of the week I managed to get to Parkgate after work. Grey, cold and windy but some decent birds nevertheless including 4 Hen Harriers (male and three ring-tails), Merlin and Peregrine.
