Population justification: The population is estimated as no more than 1,000 breeding pairs, perhaps as few as 500, and a total population of 2,000–4,000 birds.

Trend justification: The population undoubtedly declined through the 19th and 20th centuries during which time breeding populations on Guadeloupe, Dominica and Martinique may have been entirely extirpated. This decline is thought to have continued during recent years but requires confirmation.
