So, I visited den blå planet, where they keep a Red-legged k. among the black-legged and I can't tell the difference in their current plumage. Can anyone help?
Red-legged Kittiwake always has red legs, so on that alone two birds can be ruled out. Upper left bird has a bill too long to be Red-legged. Center right bird maybe, but it's hiding both ID points of legs and bill so indeterminable.
