Birdfinding.info ⇒  Locally common in several parts of its range: the western Llanos; the arid littoral of northern Colombia and northwestern Venezuela; the savannas of Roraima and western Guyana; the ABC Islands; and especially Tobago.  Consistent sites include Bubali Bird Sanctuary (Aruba); Washington Slagbaai National Park (Bonaire); everywhere on Curaçao; Little Tobago Island; Cuffie River Nature Retreat and Flagstaff Hill (Tobago); the Aripo savannas (Trinidad); Los Flamencos Wildlife Reserve (Colombia); and the Estrada Perdida in Viruá National Park (Roraima, Brazil).  Rare on Martinique, mostly at La Caravelle Nature Reserve.

White-tailed Nightjar

Hydropsalis cayennensis

Northern South America and adjacent parts of Central America and the West Indies, where it occurs in semiopen habitats: savanna, scrub, open woodlands, and forest edge.

In Central America, found nearly throughout the Pacific slope of Costa Rica and Panama, and at least locally or occasionally on some parts of the Caribbean slope.

In South America, found mainly in four regions: (1) Caribbean lowlands from Colombia east to French Guiana; (2) intermontane valleys of western Colombia and northernmost Ecuador; (3) the Llanos of Colombia and Venezuela; and (4) the Tepui region and adjacent savannas of Roraima and Guyana.

In the West Indies: the ABC Islands, Isla Margarita, Trinidad, Tobago, and a small relict population on Martinique.  Has also been recorded as a vagrant to Barbados and Puerto Rico.

Identification

A small nightjar with a broad tawny nuchal collar and strongly divergent male and female plumages.

Male has contrasty upperparts and pale underparts—but these vary from mostly white to mottled.  Typically shows bold buffy shoulder straps and rows of white spots on the wing coverts.

The male’s undertail is white with  dark band near the base that is visible when the undertail is in full view.  Its uppertail is plain when folded and shows white outer tail feathers when spread.

In flight, the male shows bright white bands on the primaries, and the underwing is largely white.

Female is cryptically patterned overall.  The female’s upperparts are generally similar to the male’s, but the underparts are usually somewhat darker and typically barred, at least on the breast.

The female’s undertail is barred, not plain white.

In flight, the female shows buffy bands on the primaries.
