Description
The least poorwill is 17 to 21.5 cm (6.7 to 8.5 in) long. The nominate subspecies' upperparts are grayish brown with blackish streaks and the folded wing shows bold white spots. It has a wide buff collar on the hindneck. The breast is dark brown with white spots and the belly white with brown bars and vermiculation. All but the central tail feathers have narrow pale tips, white in the male and buff in the female. S. b. gonavensis is thought to be smaller and paler overall.[3]
Distribution and habitat
The nominate subspecies of least poorwill is found in the central and western parts of the Dominican Republic, especially Pedernales, Independencia, and Barahona Provinces, and adjoining Ouest Department in Haiti. S. b. gonavensis is found only on Haiti's Ile de la Gonâve. The species is thought to be generally rare, although it can be locally common, and is possibly under-reported. Recorded sightings are most common in the Dominican Republic, with very few in Haiti.[1][3]

Behavior
Feeding
Little is known about the least poorwill's feeding behavior and diet, though the latter is believed to be insects.[3]

The least poorwill is believed to breed between April and June. One clutch of two eggs was laid directly on the ground with no nest.[3]
Vocalization
The male least poorwill's song is "a whistled 'toorrrrri' rising in pitch, or a warbled 'tworrri'." The species also makes "short, whistled 'toorric' or 'to-ic'" calls and "dove-like scratchy sounds".[3]
