About These Birds
Common Pochard
O pato-castanho é um grande pato mergulhador amplamente distribuído em zonas húmidas de água doce e costeiras do Paleártico. Os machos têm cabeça e pescoço ruivos, peito preto e corpo cinzento. Habita lagos, reservatórios e rios mais lentos com vegetação aquática densa. É muito semelhante ao pato-de-cabeça-vermelha americano, que é o seu equivalente no Novo Mundo. As populações europeias sofreram declínios significativos, levando a preocupações de conservação.
Mandarin Duck
The mandarin duck is widely considered the most beautiful duck in the world. In East Asian culture, mandarin ducks symbolize love and fidelity because they form strong pair bonds. Unlike most ducks, mandarins nest in tree holes up to 9 meters above the ground, and day-old ducklings must leap to the ground.
