About These Birds
Red-breasted Goose
O ganso-de-pescoço-vermelho é um ganso pequeno e marcante com padrão de coloração elaborado de castanho-avermelhado, branco e preto. Cria em tundra siberiana ártica, muitas vezes aninhando perto de falcões e corujas-das-neves para proteção. Hiberna principalmente nas costas do Mar Negro, Mar Cáspio e no nordeste de África. A espécie é classificada como ameaçada, com declínios acentuados da população nos últimos anos devido a alterações no uso da terra nos seus locais de hibernada.
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.
