About These Birds
águia-de-cabeça-branca
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
Gavião-belo
The Black-collared Hawk is a medium-sized raptor of South and Central American wetlands, with distinctive white head, chestnut body, and a black collar across the lower throat. It ranges from Mexico south through the Amazon Basin to Argentina, inhabiting the edges of rivers, lakes, marshes, and flooded forests. It feeds almost exclusively on fish, plunging feet-first into water to capture prey.
