Ganso de faces brancas, Bernaca

Barnacle goose. The barnacle goose (Branta leucopsis) belongs to the genus Branta of black geese, which contains species with largely black plumage, distinguishing them from the grey Anser species. Despite its superficial similarity to the brant goose, genetic analysis has shown it is an eastern derivative of the cackling goose lineage.
