Population justification: The population of Cuban Black Hawk is estimated at less than 2,500 mature individuals and declining (González Alonso et al. 2012); hence it is here placed in the band 1,000-2,499 mature individuals.

Trend justification: There are no quantitative data on population trends, but a slow to moderate and ongoing decline is suspected based on the intensity of drainage and wetland reclamation. Tracewski et al. (2016) measured the forest loss within the species’s range between 2000 and 2012 as c. 47 km2. This roughly equates to a rate of forest loss of 2.2% over three generation (22.8 years) for the species. Given that Cuban Black Hawk occupies both mangrove forest and open savannah (del Hoyo et al. 2019), forest loss may not drive a significant population decline.
