Brent Goose
Branta bernicla
Cadha
The Brent Goose is the smallest of Ireland's geese, being not much larger than a Mallard Duck. The pale-bellied form (the form occurring in Ireland) is greyish on the belly and flanks. Brent Geese have small white markings on the sides of the neck and the bill is very small. The young have pale edges to some of the feathers on the back. Flocks of Brents call with a low 'gurgling' noise both on the ground and in the air. They feed on eel grass and other marine plants on coastal mudflats, their primary habitat.
