Migratory status	not a migrant	Forest dependency	high

Population justification: Any remaining population is assumed to be tiny (numbering fewer than 50 individuals and mature individuals) based on the lack of confirmed records since 1956; analyses of remaining habitat indicate that no tracts remain which are large enough to support the species.
