Population justification: The global population has been estimated at c.140-260 individuals based on recent breeding season surveys. This is roughly equivalent to 93-180 mature individuals.
Trend justification: The species's population is suspected to be in decline owing primarily to the impacts of the Shiny Cowbird Molothrus bonariensis on breeding success and lethal yellowing on the availability of suitable coconut palm habitat.
