Population justification: Given the lack of confirmed sightings since 1944 any remaining population within the USA is likely to be tiny. A tiny population may also remain in Cuba, despite lack of recent sightings. Its total population, if extant, is likely to number fewer than 50 individuals and mature individuals.

Trend justification: Any remaining population is likely to be in decline owing to continuing habitat loss, in particular in Cuba, where hunting may also be having an impact.
