yellowish legged GBBG have occured ever since (in e.g. baltic sea they are a regular sight), but this year particularly there seems to be going on something in the north atlantic/north sea: colour ringed herring gulls which in other years had normal fleshy coloured legs this year show yellow legs as noted by some dutch birders. speculations goes towards nutrition with maize, but who knows what humans have have added somewhere in their feeding places.
Interesting stuff Lou, Thank you. I suppose that the leg colour is carotenoid-based, a parasite could be to blame.
yes, that's an exceptionally advanced one. reminds me of a bucharest bird some years ago..it is in fact just a 2cy |>|
no, this is a juv michahellis but i guess you've heard about that recent record of a young audouin's at kastoria lake in july? which is not that far away from you. and way more inland.
