The palm crow (Corvus palmarum ) is a relatively small corvid that occurs on the Caribbean island of Hispaniola (Haiti and the Dominican Republic) and Cuba, where it was formerly very frequent, but is now reduced in population.
The local name for the palm crow is cao in the Dominican Republic (where it is locally common, mainly in mountain pine forests and also around the area of Lake Enriquillo), which is onomatopoeic of the simple and repetitive call of this bird.
