Similar to Common Black Hawk. Differs in smaller size, overall browner plumage with conspicuous pale feather tips, larger white underwing patch, faint pale malar stripe, lack of rufous in wing panel and different vocalisations.

Distribution

Endemic to Cuba and Isle of Pines.

Taxonomy

This is a monotypic species[1].
Formerly classified as a subspecies of Common Black Hawk.

Habitat

Mostly near coast in and adjacent to mangrove forest; less often seen on sandy beaches. Mainly in lowland near swamps and small islands, both in coastal forest and more open areas.

Behaviour

Actions

Flight: likes to alternate flapping and gliding, even though it can soar.

Breeding

Nests from January through June. Seven of eight nests examined from mid- to late May 1996–1998 contained eggs, and one had a nestling.

Scans for prey from perch in tree or from ground. Feeds heavily on crabs, also fish carrion, rodents and lizards.

Vocalisations
