Kara Atmaca Kartalı Spizaetus tyrannus

Uncommon, spectacular, crested eagle of lowland tropical forest. Most frequently seen soaring in mid-late morning; rarely seen perched. Gives loud, far-carrying whistles while flying, which often indicate its presence. Adult is black overall with bold white checkering under the wings and bold white bands on the tail. Immatures, although rarely seen, are browner with a white throat and crown. The short bushy crest is usually apparent only on perched birds and is not seen in flight.
