About These Birds
Black Swan

Velvet Scoter
O pato-fusco é um grande pato marinho da Europa e Ásia. Os machos são principalmente pretos com uma mancha branca embaixo do olho e bico laranja-amarelo com tubérculo. Cria em zonas húmidas florestais do norte da Europa e Ásia e hiberna em costas marinhas. As populações sofreram declínios significativos em algumas partes do seu alcance, particularmente na Escandinávia. A espécie é agora dividida nalgumas classificações nas espécies pato-fusco, pato-fusco-de-asa-branca e pato-fusco-de-veludo.
