Site description The Dos Pos/Roi Sangu IBA is at the north end of Bonaire on the leeward side of the island. It lies south east of the Washington Slagbaai National Park IBA and immediately east of the Gotomere Lake. The area is characterised by numerous small hills and sheltered valleys.

Key Biodiversity • This IBA is important for the Yellow-shouldered Amazon, the Bare-eyed Pigeon, Pearly-eyed Thrasher and Caribbean Elaenia • The population estimate for the Yellow-shouldered Amazon is 650 individuals on the island (January 2007 estimate). • In winter 40% of the island’s parrot population roosts in the IBA: 267 birds are in three separate roosts, the third, forth and fifth largest roosts on the island. • Following island wide searches by researchers and a team of volunteers this area represented 20% of known parrot nests (6 pairs). • In 2007 fledglings from this area represented 43% of known fledglings for the parrot population. • Dos Pos is a valuable location for migrating passerines including Scarlet and Summer tangers Blackburnian warblers and Rose- breasted Grosbeaks. Peregrine flacons and Merlins are frequent winter vistors to this area.
