About These Birds

Red-legged Sparrowhawk

The Red-legged Sparrowhawk, <em>Accipiter erythropus</em>, is a small raptor in the family Accipitridae (Hawks, Eagles & Kites). It inhabits forest environments, consistent with the arboreal hunting style characteristic of accipiters. Detailed plumage and behavioral descriptions of this species are limited in the available literature. The species is assessed as Least Concern on global conservation evaluations. Available nesting data indicate a clutch size of 2 eggs, though further details on nest structure, incubation duration, and fledging period are not documented here. …

Harpy Eagle

The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
