From the IUCN Red List Species Account:


Range Description

This species is endemic to central Jamaica. It formerly occurred on the south-western coast, at an altitudinal range of sea level to 1,200m asl.

Habitat and Ecology

This species is found in mesic broadleaf woods and forests on tree trunks and in bromeliads; it requires large dead trees. Males call from hollows in branches and bromeliads, and eggs are laid in bromeliads. It is not found in significantly altered habitats but can be found in regenerating forests.


There has been a decline in its abundance, and this species is now rarely encountered or heard calling, except in pockets of suitable habitat.

Population Trend


Major Threats

It is threatened by habitat degradation and deforestation due to agriculture, human settlements, development for tourist activities, and logging.

Conservation Actions

It occurs in several forest reserves, but these do not guarantee the species' long-term protection, and increased management of these, and improved habitat protection, are necessary.

Red List Status

Endangered (EN)


Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in Jamaica.
