The Hispaniolan palm crow (Corvus palmarum) is a relatively small corvid is endemic to the Caribbean island of Hispaniola (in Haiti and the Dominican Republic) where it was formerly very frequent, but is now reduced in population.

Taxonomy

The Hispaniolan palm crow was formally described in 1835 under the binomial name Corvus palmarum by the German naturalist Duke Paul Wilhelm of Württemberg.[2] The species is monotypic: no subspecies are recognised.[3] This crow was formerly considered to be conspecific with the Cuban palm crow (Corvus minutus).[3][4][5]

Despite being sympatric with the white-necked crow (Corvus leucognaphalus) on Hispaniola, it appears to be more closely related to the fish crow (C. ossifragus) of the East Coast of the United States, as well as two smaller species, the Tamaulipas crow (C. imparatus) and Sinaloan crow (C. sinaloae) of Mexico, than the white-necked crow, which is more related to the Cuban crow (Corvus nasicus) and the Jamaican crow (Corvus jamaicensis), the other two Caribbean corvids.

The following cladogram is based on phylogenetic study of the Corvidae by Knud Jønsson and collaborators that was published in 2012.[6]

Hispaniolan palm crow, Corvus palmarum

Cuban palm crow, Corvus minutus

Fish crow, Corvus ossifragus

Sinaloa crow, Corvus sinaloae

Tamaulipas crow, Corvus imparatus

The species was formerly considered to be conspecific with the Cuban palm crow (Corvus minutus).

Habitat

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.
