Birdfinding.info \u21d2\u00a0<\/em><\/strong> Endangered, declining, and disappearing from some parts of its range.\u00a0 Abaco is the Bahama Swallow\u2019s last true stronghold\u2014although the full impact of Hurricane Dorian in September 2019 remains uncertain.\u00a0 Prior to Dorian, it could be found reliably year-round nearly throughout Abaco, especially from Marsh Harbour south to Abaco National Park, and in the north at Treasure Cay.\u00a0 On Grand Bahama, where Dorian\u2019s impact was even stronger, it has traditionally been found most consistently in Freeport and at Freetown Farm.\u00a0 On Andros, it has become uncommon but still usually present in small numbers at various sites from Nicholls Town to Andros Town.\u00a0 No longer resident on New Providence, but small numbers continue to appear unpredictably anywhere around the island at any time of year.\u00a0 In Cuba, it has been regular in recent winters on Cayo Guillermo.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Endemic to the Bahamas<\/strong>, where it breeds on Grand Bahama, Abaco, and Andros.\u00a0 Formerly also on New Providence, where it become an occasional visitor, and it appears to be on the verge of disappearing from Grand Bahama as well.<\/p>

Some nonbreeders remain on the breeding grounds, while others disperse southward into the central Bahamas and in small numbers, or sporadically, to the southern Bahamas, Turks & Caicos, and the north-central keys of Cuba.<\/p>

In 2016, IUCN estimated its total population at somewhere between 1,500 and 4,000 individuals, less than half of the 1989 population estimate.<\/p>

There are about a dozen records from southern Florida\u2014most in spring and summer on the Florida Keys in the 1970s and \u201880s.\u00a0 One famous individual summered annually at a Cave Swallow colony at Cutler Ridge in South Miami from 1988 to 1992.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In flight, the undersides of the wings show white linings, which distinguish it from all similar species likely to overlap with it.\u00a0 Both adults and juveniles have this diagnostic feature.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
