Abstract:
The purpose of this paper is to rapidly disseminate recent findings concerning the taxonomic and conservation status of the Brown-headed Nuthatch population on Grand Bahama. Heretofore, this population has been regarded as conspecific with continental populations of the Brown-headed Nuthatch (Sitta pusilla) in the southeastern United States. However, on the basis of morphometric differentiation and very distinctive vocalizations, we propose recognition of the Bahama Nuthatch (S. insularis) as an endemic, full species. Population surveys conducted on Grand Bahama in 2004 suggest this species is endangered, with hundreds to possibly a few thousand individuals remaining. These birds require mature, fire-maintained stands of Caribbean Pine (Pinus caribaea) and face serious threats associated with accelerated development, potential logging, invasive species (including snakes, cats, raccoons, and competing cavity-nesting birds), and catastrophic storm damage. Thus, the species may become extinct unless Bahamians are willing to take action to save it. We offer several suggestions to begin formulating a management plan. As the rarest bird in the Bahamas, and one of the rarest birds in the world, the nuthatch will become a high-profile symbol of conservation efforts (or their failure) in the Bahamas.
