 The brown-throated parakeet ("Aratinga pertinax"), introduced to the island, is rarely seen.The scaly-breasted thrasher ("Allenia fusca") may have become extirpated from the Island.A resident race of the yellow warbler ("Dendroica petechia petechia") is also threatened, mostly due to loss of its mangrove swamp habitat; the last major refuge for this species is the Graeme Hall Swamp in the south of the Island, However some reports suggest the species is expanding its range on the island.
