About These Birds
Mottled Duck
O pato malhado é um pato dabbling residente das zonas húmidas costeiras do Golfo do México e da Flórida. É o único pato dabbling não migratório a criar no sul da Flórida. Apresenta uma coloração castanha mosqueada com cabeça mais pálida e bico amarelo-esverdeado nos machos. Habita pântanos de água salgada e salobra, zonas húmidas costeiras e arrozais. As duas subespécies principais são o pato malhado da Flórida e o pato malhado do Golfo.
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
