The globally threatened Blue-headed Quail Dove, a Cuban endangered endemic is recorded occasionally. It is the only recorded location on TCI for this species but its rare occurrence does not qualify the site for A1 status. The site is important for restricted-range species including the Pearly-eyed Thrasher, , for which it is probably the most important area in TCI. Also the Bahama Woodstar and Thick-billed Vireo. Biome-restricted species include: Key West Quail-dove for which it is probably the most important area in TCI, Stripe-headed Tanager and the Cuban Crow. The site contributes to a network for these species,
