đại bàng đầu trắng
High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.
Keel-billed Toucan
Produces a repeated frog-like croaking 'prrrek-prrrek' or 'terrio-terrio'. Not melodic; the call resembles a mechanical rattle or frog. Also gives bill-clattering.

About These Birds
đại bàng đầu trắng
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.
Keel-billed Toucan
The keel-billed toucan is the national bird of Belize and one of the most recognizable birds in the Neotropics. Its oversized bill, which can be a third of its body length, is actually very light due to its hollow honeycomb structure. Toucans roost communally, with up to six adults squeezing into a single tree cavity.
