Bahama Swallows breed only on the islands of Andros, Abaco, New Providence, and Grand Bahama in the northern Bahamas (American Ornithologists’ Union 1998); now rare (Brudenell-Bruce 1975) or perhaps extirpated (Raffaele et al. 1998) from New Providence, however.
At least part of the population moves south after breeding. Reported to be "probably a rare transient and occasional winter visitor" in the southern Bahamas (Buden 1987), and as a "rare winter resident (30 Jan-8 Mar.)" in Cuba (Garrido and Kirkconnell 2000).
The Bahama Swallow occurs only a low elevations.
There is a record of one specimen of Bahama Swallow that was collected at the Dry Tortugas, Florida (Smith and Smith 1989). Smith and Smith (1990) reviewed almost 25 additional sight records from Florida, of which at least eight were judged to be "reasonably certain" to refer to Bahama Swallow. Smith and Smith (1990) pointed out that "all reasonably certain and most uncertain [unconfirmed] reports fall between the dates of 19 March and 26 August, and most are from summer," and speculated that the Bahama Swallow occurs in Florida "fairly regularly after breeding."
