The Eurasian Coot is recognised by its snowy white bill and forehead shield. The remainder of the bird is dark sooty grey, except for its bright red eye. Immature birds are generally paler than adults with a white wash on the throat. It is able to compress its feathers and squeeze out all of the air, which allows it to dive deeply and for longer periods.
