アカクロクマタカ Spizaetus isidori

Rare, crested eagle of middle- to upper-elevation cloud forest. Adult’s plumage is mostly black with chestnut on breast and belly. In flight, note large white patches in wings and at base of tail, and chestnut in underwing. Juvenile is amazingly different with dark back, white underparts, and strongly banded wings and tail. Juvenile similar to pale morph Crested Eagle, but wing and tail banding is thinner, and lacks barring on breast and belly. Most likely encountered on sunny mornings, when single birds or pairs may soar high over forested ridges.
