YLG Update

Further to my sighting on 13th September of a possible Yellow-legged Gull on Castle Lake, Stephen Buckle has kindly sent me an e-mail concerning an interesting bird he saw there on 30th August. (Apologies to Stephen for not posting this earlier).

Stephen describes the bird as follows;

Bird is a Herring Gull type which I aged as (moulting into?) 3rd winter as it had some pale faded brown on the upper row of coverts (not clearly visible in the photos).  My attention was drawn to it because it had much darker shade of grey to the back than argenteus Herring Gull, in fact side-by-side with adult Common Gulls you could see it had a slightly darker shade than them.  It was however (in my view) nowhere near dark enough to be an LBBG.  The bird also seemed to have a lot of red on the distal part of the bill.

These features got me excited about the possibility of Yellow-legged Gull but when we (myself and a friend I was with) got a clear view of the legs they were pale pinkish i.e. looked like those of a Herring Gull.  I said to my friend that it could not be a YLG, but could be a Scandinavian Herring Gull.

On the standing bird, the wing tips looked completely back with no white tips to the primaries.  I didn't get a good view of the spread wing, partly because I wasn't sure how helpful this would be on an immature / moulting bird, but probably also due to lack of confidence that I'd be sure of what I was seeing during brief flaps.  In hindsight I probably should have tried to get a photo or at least a good view of the spread wing.


It certainly appears that this Gull is a strong candidate for Scandinavian Herring Gull despite the early date and inland location.
Many thanks again to Stephen for the photo's and description.

Back In The Village...

...is the name of an Iron Maiden song that I find myself singing as I drive into Bishop Middleham but by the time I've reached the hide the tablets have kicked in.


Back down this evening, now that I'm starting to get into Gull's (it won't last), I thought I'd grill each and every one but its a bit daunting when they are all over the place. Tonights totals went something like this;
Black-headed Gull 170
Lesser Black-backed Gull 1 adult
Common Gull 30
Herring Gull 50 flew in together from the south, apart from 2 adults and a 2nd winter the others were all 1st-winter birds.

Other movers and shakers included 52 Teal, 2 Kestrel, 3 Ringed Plover, 6 Ruff (4 of which later relocated to the A1 Flashes), 1 Dunlin, 1 Snipe and 6 Curlew.

A tractor ploughing the field next to Stoneybeck Lake resulted in only 5 Moorhen of note.
