Sitta insularis
The Bahama Nuthatch (Sitta insularis) is a diminutive and critically endangered, likely extinct, passerine endemic to the pine forests of Grand Bahama Island. Measuring approximately 10 cm (4 inches) in length and weighing around 10.5 grams, it presents a striking appearance with blue-gray upperparts, pristine white underparts, and a distinctive black crown that contrasts sharply with a prominent white supercilium and a black eye-stripe. Unlike many of its Nuthatch relatives, it lacks any ruf...
Primarily inhabits mature, old-growth Caribbean Pine (Pinus caribaea var. bahamensis) forests in lowland areas, rarely venturing into mixed woodlands. It depends entirely on these specific trees for foraging, nesting, and shelter.
Feeds primarily on insects and their larvae, including beetles, spiders, and other small arthropods, meticulously extracted from pine bark crevices. It may also consume some pine seeds, especially during leaner insect periods.
A diurnal species, the Bahama Nuthatch exhibited classic nuthatch foraging behavior, meticulously working its way head-first down tree trunks and branches, probing deep into bark crevices with its specialized bill. It primarily sought out arthropods hidden within the rough bark of Caribbean Pines...
The Bahama Nuthatch was historically endemic to the island of Grand Bahama in the Bahamas archipelago. Its range was highly restricted to mature, old-growth Caribbean Pine (Pinus caribaea var. bahamensis) forests. Prior to 2016, its distribution was already fragmented, confined to a few isolated ...
