About These Birds
West Indian Whistling-duck
O parreco-cubano é um pato assobiadeiro grande encontrado nas Antilhas, principalmente Cuba, Jamaica, Hispaniola e ilhas adjacentes. Tem coloração escura com ventre e flancos fortemente malhados de branco. Habita zonas húmidas costeiras, manguezais e lagoas de interior. É o maior pato assobiadeiro. Está classificado como vulnerável devido à perda de habitat e caça. Como outros parrecos, empoleira-se em árvores e é mais ativo ao anoitecer e ao amanhecer.
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.
