Description

Barrow’s goldeneye is a medium-sized, stocky diving seaduck with a large, oblong-shaped head. It is named after the English geographer and linguist, Sir John Barrow.

The adult Barrow’s goldeneye is similar to the common goldeneye. The male has a dark triangular-shaped head with a purple gloss, and a white crescent at the front of the face just behind the bill. It has a white belly and small white spots along the black wings. The eyes are bright yellow and the bill is dark. Females are grey with a copper-brown head and yellow bill. They are smaller than the males.

They spend much of their time on water, and have a stiff flight with rapid wingbeats but can fly easily through dense forests. Females can often be heard calling as they fly.
