Hi All,

I took these pictures of this strange (to me) gull today at my local spot near Debrecen, Hungary.

Is it possible that it's a HG or just a YLG with unusually pale tertials and greater coverts?

And also it should be a 1cy bird shouldn't it?

Thanks in advance,

Gabor

In my humble opinion it is a 1cy Yellow-legged Gull. For some variations in the juvenile plumage for eastern YL Gulls see my posts from here: viewforum.php?f=24

Those pale feathers aren't juvenile, they are second generation feathers. You can see exactly where it stopped the replacement in the open wing shot. Nice 1cy YLG!

thanks guys.

it crossed my mind that it's already second generation but I didn't think that they can be that advanced at around now. most YLGs I see at this spot aren't near to this one. and I don't think I have ever seen so pale and unmarked greater coverts like this one has.

cheers,

Gabor
