Gull IDs Derbys/Notts UK (1 Viewer)

[ChrisLuv]

Hi all,

First of all sorry for the dodgy photos, they were all taken at long range - one through my scope. My gull IDs aren't the best so thought I'd pos

First two are different birds, both taken yesterday - first at Carsington where a Yellow-legged gull has been hanging round for a month. Second was taken at Attenborough.

Third pic was also at Attenborough yesterday

I'm thinking first is Yellow-legged, second is Lesser Black-backed and third is black headed (the reason I'm posting is the back looked very dark for a black headed gull).

Thanks,
Chris

Not sure about the first two but the last one is a juvenile Common Tern.

Blast - a tern never crossed my mind. Thanks Andrew.

Herring gull (3cy?), LBB Gull, Juv common tern...

hi,

first one looks like an adult (or 4cy+) herring gull though it's impossible to exclude YLG.

second looks like it has pinkish feet which is not so good for adult LBBG although in such a digiscoped pic colour aberration can be strong. structurally better for LBBG though not impossible for a female GBBG (which usually has pinkish legs as opposed to yellow in LBBG).

Legs are yellow on my monitor???

hi chris, have a look at my digiscoped pics from carsington, the link to the album, i believed it to be the yellow legged gull, but never saw it out of the water, then the single pick was taken the next day which was a Yellow Legged Gull, their head patterns were the same! I think you could well have the YLG there, Do you have any other pictures of the black backed gull? It looks to me like incredibly harsh lighting, i wanted to say lesser black backed, but i do agree with lou's comment

Hi Lou - legs were definitely yellow in the second bird (thats why I took the photo - as at the time I was thinking YLG) but its generally a much darker bird than the first photo - which I'd say makes it good for LBBG.

I'll post some other photos of the second bird tonight, though I think they'll all be of similar quality.

Thanks for replies so far, Chris.

More pics of second bird

I promised more pictures of the BBG (one digiscoped / one not) - but not sure if they will help us reach a consensus, the quality ain't great. Personally I'm in the LBBG camp - but I'm no expert.

Thanks for your input.

me to, chris, structurally it looks better for LBBG but as said, with the reservation that a smallish female GBBG could look similar. tertial crescent looks broad for LBBG but again, this could be a photo trick. hint of a small mirror looks lbbg-ish but, there's too little detail visible to be 100% sure.

Thanks Lou. For future reference what do mean by "hint of a small mirror"?

 

[lou salomon]

in adult large gulls mirrors are the larger white spots close to the tip of the outer primaries, p9 and p10. i was wrong though with calling the white spot visible in the wingtip a mirror, it's probably one of the white tips of the primaries, different to mirrors. see topography e.g. here: http://www.iesmeulmeester.nl/index.php?id=6 - 3rd pic, left wing.
