Bahama Swallow
Tachycineta cyaneoviridis
An elegant aerial hunter most often found in pine woodlands, but also seen in towns and over fields. Note the long forked tail, green to blue-green upperparts, and white underparts. Tree Swallows are similarly colored, but have a shorter, notched tail. Tree Swallows also have entirely dusky underwings unlike Bahama Swallows which have white armpits. Calls include a slightly squeaky “chet” or “chet-chet” and a thin “tsi-tsip.” Song is a beautiful liquid jumble of rich notes.

分布与栖息地
This swallow breeds only in pineyards on four islands in the northern Bahamas: Andros, Grand Bahama, Abaco, and New Providence. The breeding population on New Providence is, at the very least, greatly reduced from historical levels, and may be extirpated as a breeding species.<p>The Bahama swallow winters throughout the eastern Bahamas and the Turks and Caicos Islands. It is a rare vagrant elsewhere during migration, including south Florida, the Florida Keys and Cuba. It is also an occasional vagrant to South America.<p>T. cyaneoviridis is endemic to the Bahamian pineyards, though they are somewhat capable of adapting to urban habitat. Although they do not breed in marshland and fields, they need such habitat to forage; like all swallows, they feed on flying insects.

Short-tailed Nighthawk
Lurocalis semitorquatus
Dark nighthawk, most often seen flying over the forest canopy or a river at dusk. Overall brown with richer rufous belly and underwings; small white throat patch is sometimes difficult to see. Short tail is noticeable in flight. Unlike many other similar species, does not show white patches in wings. Sexes alike. Even less conspicuous than other nighthawks, often appearing fleetingly in the twilight and very rarely seen roosting during the day.
Yellow-billed Tit-Tyrant
Anairetes flavirostris
Active little bird of scrubby and brushy habitats in drier regions of the Andes and locally in the lowlands of Argentina. Often in pairs, hopping in bushes and weeds and can be difficult to see well. Best identified by bold blackish striping on breast and wispy black crest. Note the base of bill is bright orange (not yellow!), but difficult to see in the field.
Northern Marquesan Reed Warbler
Acrocephalus percernis
A large, seemingly long-bodied warbler, mostly bright yellow with some greenish-olive above. Bill and tail long. Often perches in a flat stance, making it look banana-like. Most common in dense brush and thickets with dense tangled understory. Song is a loud and long sequence of warbled phrases and “churr” notes. Calls include harsh churring and “tchak” notes.
