What do seabirds look like?

Plumage Coloration: Most seabirds have drab plumage that is dark above and light below.

Wing Shape: Seabirds' wings are specially shaped for their unique flight needs.

In seabirds of any size the oscillating mode of flight tends to go with relatively narrow wings, which may be beaten the more rapidly because, by their narrowness, they present less surface to the resistance of the air. The limited wing-surface, in turn, may represent an adaptation to an environment of strong winds.
