Appearance: The Black Hawk-Eagle is a striking bird of prey with a prominent crest and long tail. Adults typically have blackish-brown upperparts and white underparts. They have a black band across their chest and are adorned with barred black-and-white tail feathers. This species also has yellow eyes and a powerful, hooked beak.

Habitat: Black Hawk-Eagles are found in a variety of forested habitats, including tropical and subtropical forests, montane forests, and sometimes in open woodland areas. In Colombia, they can be seen in the diverse forested regions across the country, including the Andean slopes and other mountainous areas.

Behavior: These eagles are specialized hunters that prey on birds and mammals. They are agile flyers and are known for their stealthy hunting techniques, often perching high in the canopy before swooping down swiftly to catch their prey. They are also territorial birds, defending their nesting areas from intruders.

Breeding: Breeding typically occurs during the dry season when food is abundant. Black Hawk-Eagles construct large stick nests high in trees, where the female lays a single egg or occasionally two eggs. Both parents participate in incubating the eggs and raising the young eaglet(s), which fledge after several months.

Conservation Status: The species is not globally considered threatened and is categorized as being of Least Concern by the IUCN.
