Distribution and habitat

The Jamaican lizard cuckoo is found throughout the island from sea level to of elevation. It primarily inhabits lowland tropical evergreen forest and is also found in tropical deciduous forest, more open woodlands, and semi-arid landscapes of trees and shrubs.

Behavior

Movement

The Jamaican lizard cuckoo is not migratory.

Feeding

Breeding

has assessed the Jamaican lizard cuckoo as being of Least Concern, though it has a rather small range and an unknown population size that is believed to be decreasing. No immediate threats have been identified. It is widespread on the island but uncommon, and "further research is required to determine various aspects of its breeding."
