Conservation Actions Underway
Both known areas area protected, and the species is probably secure as long as suitable habitat is maintained in these reserves (Cruz and Delannoy 1984). In July 2011 Sociedad Ornitológica Puertorriqueña (SOPI), in collaboration with BirdLife, started a project which aims to carry out surveys for the bird in the Carite Commonwealth Forest and surrounding, privately-owned, potential habitat to determine the presence of a potential third population (V. Anadon in litt. 2012).
