About These Birds
American Black Duck
O pato-negro americano é um pato dabbling robusto encontrado no leste da América do Norte. É estreitamente relacionado com o pato-real e os dois hybridizam extensivamente. Apresenta uma plumagem escura castanho-preta característica com cabeça mais pálida e espelhos violeta nas asas. Habita zonas húmidas costeiras e de interior, florestas e pradarias ao longo das regiões orientais. É uma espécie cinegética importante, mas as suas populações diminuíram devido à hibridização com patos-reais e perda de habitat.
