Year Published: 2015
Date Assessed: 2015-10-01

Justification:
This species is considered Endangered owing to its very small and severely fragmented population, which has continued to decline until very recently. Trends appear to have stabilised or even reversed over the last five years, and if this is confirmed the species may warrant downlisting to Vulnerable in the future.

Geographic Range [top]

Range Description:The species has never been common, but formerly occurred throughout Cuba. It is now very rare and local, with five main population centres known to remain. The total population was estimated at 150-200 pairs in 1994. There are three centres for the nominate race in west and central Cuba, but two of these held only three and 20 pairs respectively in 1994. There are two further areas important for the race wileyi in the east of the island, where the bulk of the population resides. Sightings around Pico Turquino are scarce, but a bird was seen on the north slopes of the Sierra Maestra in early 1999 (Rompré et al. 2000).

Population [top]

Population:The population is estimated to number c.400 individuals, equivalent to c.270 mature individuals.

Trend Justification:  The species is suspected to still be slowly declining, owing mainly to habitat loss and persecution. However, recently trends appear to have stabilised or even reversed, with more frequent sightings over a five-year period (A. Kirkconnell in litt. 2012). Further work is needed to confirm these trends.
Current Population Trend:Decreasing
Additional data:
♦ Number of mature individuals:270♦ Continuing decline of mature individuals:Yes
♦ Extreme fluctuations:No♦ Population severely fragmented:Yes
♦ No. of subpopulations:5♦ Continuing decline in subpopulations:Yes
♦ Extreme fluctuations in subpopulations:No♦ All individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:It is found up to 800 m in a variety of wooded habitats including humid, dry and pine forests (Bierregaard 1994a). It preys mostly on birds, including poultry. The breeding season is February-May, with young fledging by June (Bierregaard 1994a, A. Kirkconnell in litt. 1999). The nest is generally placed close to the trunk of a high tree, but below the canopy.

Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):7.2
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Habitat loss and disturbance as a result of logging and agricultural conversion, and human persecution (because it preys on poultry) have been the chief causes of its  decline (A. Kirkconnell in litt. 2012). There are records of young being taken from the wild for trade (Bierregaard et al. 2014).

Conservation Actions [top]

Conservation Actions: Conservation and Research Actions Underway
CITES Appendix II. Populations occur within the Sierra Maestra and Sierra del Cristal National Parks. Environmental education has grown in Cuba in recent years (A. Kirkconnell in litt. 2012).
 

Conservation and Research Actions ProposedSurvey Pinar del Río province and the Zapata swamp, and re-survey areas in eastern Cuba to determine current populations and assess trends. Further define the species's ecological requirements. Conduct education and public awareness campaigns to highlight the plight of the bird and discourage human persecution (A. Mitchell in litt. 1998).
