Corvus leucognaphalus (White-necked Crow)

Wikipedia Abstract

The white-necked crow (Corvus leucognaphalus) is the largest (42–46 centimetres or 17–18 inches in length) of the four Caribbean crow species. Two other species, the Cuban crow (Corvus nasicus) and the Jamaican crow (Corvus jamaicensis), appear to be very closely related to it sharing several key morphological features. The fourth species from this region, the palm crow (Corvus palmarum), would appear to be a later arrival (at least in evolutionary terms) and shows affinities with the fish crow (C. ossifragus) of North America and two Mexican species.
