Site description
The site occupies 427 ha of tall dry forest on karstic limestone, of which 82 ha is protected as the Parrot Reserve, owned by the National Trust. The forest is highly diverse with Cedrela odorata (the majority are mature or dead trees, main parrot nesting habitat), Sideroxylon salicifolium, Exothea paniculata, Chionanthus caymanensis and Bursera simaruba as dominants. There has been a long history of disturbance by logging and the forest is a mosaic of primary and second growth trees with, on the south of the bluff, Pilosocereus sp., Agave sobolifera, Tillandsia sp. and orchids.

Key biodiversity
These include 60-70 pairs of the Near-threatened Cuban Parrot hesterna. It is estimated that 29-42 nests per year may be necessary to sustain the population - a concern since all active parrot nests located in surveys (1999-2003) were in dead or dying Cedrela odorata cavities in the Bursera-Exothea- Chionanthus community, and while cedars were common there was no recruitment of seedlings or young trees. Since 1999, a total of 18 active nests have been located, together with other pairs holding territories but not nesting. Also, about 9% of the global population of the Near-threatened restricted-range Vitelline Warbler crawfordi. The restrictedrange Thick-billed Vireo alleni is common and the biome species Loggerhead Kingbird caymanensis is uncommon.A total of 19 taxa breed, three additional species with endemic races: Red-legged Thrush Turdus plumbeus coryi confined to Cayman Brac), Caribbean Elaenia caymanensis and Bananaquit sharpei. Indigenous species are the Whitecrowned Pigeon, Zenaida Dove, White-winged Dove, Common Ground-dove, Mangrove Cuckoo, Smooth-billed Ani, Barn Owl, Northern Mockingbird and Yellow-faced Grassquit Tiaris olivaceus; summer breeding migrants are the Grey Kingbird, Antillean Nighthawk and Blackwhiskered Vireo.Regular migrant landbirds include Yellow-bellied sapsucker, Grey Catbird, White-eyed Vireo, Yellow-throated Vireo, and 28 species of warbler, most commonly Northern Parula, Cape May Warbler, Yellow-rumped Warbler, Yellow-throated Warbler, Palm Warbler, Prairie Warbler, Black-and-white Warbler, American Redstart and Ovenbird.
