Distribution
Cordillera Central of Dominican Republic and adjacent Haiti.
Vagrant in Jamaica.
Taxonomy
It was formerly regarded as conspecific with the Two-barred Crossbill Loxia leucoptera, from which it is now assumed it evolved.
It has been suggested that the origin of L. megaplaga can be traced to southern populations of L. leucoptera which got stranded on the highest pine-forested mountains of Hispaniola (the highest in all the Caribbean islands) when the glaciers and the cold started receding northward, as did the vast coniferous forests, after end of the last ice age, when the Holocene epoch began, some 10,000 years ago. The distance that now separates both species is of thousands of kilometers (from the Caribbean to the northern U.S. and Canada), making the story of the Hispaniola Crossbill an interesting one from an ecological and environmental point of view.
This is a monotypic species[1].
Habitat
Hispaniolan Pine Pinus occidentalis forests.
Behaviour
Diet
Feeds almost exclusively on the seeds of Hispaniolan Pine, extracted from the cones by twisting its bill between the cone scales.
Breeding
They construct a deep cup nest from a variety of materials such as twigs, plant fibres, roots, moss, lichens, bark strips, grass, animal hair and feathers.
