I am not very familiar with Divers/Grebes, especially in their winter plumage. In clearer photos, I identified R-T Divers and Slavonian Grebes for sure, but I am left with the attached photos (at distance in poor light) where I am not 100% sure for one reason or another.
Photo 1 - R-Ts?
Photo 2 - Bird furthest to the right looks to have peaked head, although beak still looks R-T to me?
Photo 3 - Dark half collar on this bird. Still a R-T?
Photo 4 - Bird to right of Scoter in flight. Is bill a little heavy or is it another R-T?
Photo 5 - Is that a dark collar?
