Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Contributor(s): Mitchell, A.
Facilitator/Compiler(s): Mahood, S., Sharpe, C.J.
Justification:
This species has been classified as Near Threatened because although it can be locally common, it has a specialised habitat and consequently a moderately small range which is likely to be contracting owing to drainage and other forms of wetland destruction. However, given the dispersal capabilities of large raptors, the habitat and population is unlikely to be severely fragmented or restricted to few locations.

Geographic Range [top]

Range Description:Buteogallus gundlachii is endemic to Cuba, Isla de Pinos and several larger cays where it is generally relatively uncommon and quite localised (Wiley and Garrido 2005). However, within optimal areas it can be quite common, such as in the northern cays (Romano, Paredon Grande, Coco) and in the Zapata Swamp (A. Mitchell in litt. 2007).

Countries occurrence:

Cuba

Population [top]

Population:The population is estimated to number at least 10,000 mature individuals, roughly equivalent to 15,000 individuals in total.

Trend Justification:  There are no quantitative data on population trends, but a slow to moderate and on-going decline is suspected based on the intensity of drainage and wetland reclamation.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:10000Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:It is an inhabitant of mangrove swamps and the banks of large rivers. It feeds predominantly on crabs.

Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):7.6
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): It is suspected to be declining as its specialised habitat is being drained and degraded (Wiley and Garrido 2005). However, there is little data on population trends.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None is known.

Conservation Actions Proposed
Survey to assess population size. Regularly monitor at certain sites throughout its range to determine population trends. Monitor trends in destruction of suitable habitat. Protect significant areas of suitable habitat, particularly in its strongholds.
