About These Birds
Pink-footed Goose
O ganso-de-bico-curto é um ganso cinzento médio que cria na Islândia, Gronelândia e Svalbard. É facilmente identificado pelo seu bico curto e cor de rosa-cinzento com banda rosada, pernas cor-de-rosa e pescoço castanho escuro. Hiberna no Reino Unido e Países Baixos em grande número. Alimenta-se principalmente de pasto e culturas agrícolas. As populações aumentaram nas últimas décadas devido a proteção e disponibilidade de culturas agrícolas nos locais de hibernada.
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
