Similar Species

Similar to Cuban Crow but is smaller, with shorter wings. These give it a less ponderous flight action with faster wing beats.

Generally stated to have a shorter bill and elongated tufts over the upper mandible compared with that species. In Cuban Crow the nasal tufts do not cover the nostrils. However, these bill characters can be difficult to judge and seem variable (based on ebird photos).

Voice is the best distinction, but failing that the gape of Cuban crow reaches to at least the middle of the eye whilst that of palm crow stops short of it.

Distribution

Dominican Republic, Haiti and western Cuba.
Formerly abundant and still not uncommon on Hispaniola. Rare and local in Cuba, confined to Camaguey province now.

Taxonomy

Two subspeces recognized:

Both subspecies are sometimes treated as full species.

Appears to be closely related to the Fish Crow of the eastern seaboard of the United States and also two smaller species, the Tamaulipas Crow and Sinaloa Crow of Mexico and forms a species group with them.

Habitat

Mountain pine forests, arid brush and hill country. Also in lowland cultivation with some palm trees. Often between 1300 - 1900m on Hispaniola.

Behaviour

Feeds on invertebrates (beetles, caterpillars, cicadas, snails), liards and fruits. Usually foraging in pairs or small groups on the ground.
Breeding season from March to July in Cuba. Obviously a solitary nester. The nest is made of sticks and placed among tree branches or in a palm tree. Lays 4 eggs. Breeding habits poorly known.
No information about movements.
