About These Birds
Long-tailed Duck
O pato-de-cauda-longa é um pequeno pato marinho do Ártico com plumagem marcantemente diferente entre estações. Os machos têm longas plumas centrais da cauda e mudam de plumagem amplamente branca no inverno para mais escura no verão. Chama frequentemente e de forma exuberante durante o voo. Cria em zonas húmidas da tundra ártica e hiberna em costas marinhas e grandes lagos. As populações têm sofrido declínios substanciais em algumas regiões, levantando preocupações de conservação.
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.
