Birdfinding.info ⇒  Widely distributed across Cuba, but uncommon and local overall.  It seems to be most readily found in the Zapata Swamp region, especially at Playa Larga, Soplillar, and Bermejas.  Other areas where it can generally be found include Cayo Coco and the vicinity of Guardalavaca in Holguín.

Cuban Nightjar

Antrostomus cubanensis

Endemic to Cuba and its satellites, including the Isle of Youth and the Jardines del Rey Archipelago, where it inhabits various types of woodlands.  Occurs at all elevations, but seems to be most numerous in humid lowlands.  Apparently much less numerous in the southeast.

Identification

A medium-large, blackish-brown nightjar with an extensive white or cream-colored tail-tip visible from below and conspicuous gray straps on the back.

Male’s uppertail has small white corner patches.  Female’s uppertail has buffy corners that are rarely visible when the tail is folded.

Voice.  Song is a liquid trill with a somewhat musical quality, on an even tone; often repeated many times in rapid succession:

Cf. Chuck-will’s-widow.  From September to May, Cuban Nightjar shares its range with non-breeding Chuck-will’s-widow, which is very similar but somewhat larger and usually a paler, warmer shade of brown overall.  Cuban can often be recognized by the pale gray straps on its back.  Male Cuban can also be identified by the white corner patches on its uppertail, whereas male Chuck-will’s-widow has white only on the inner webs of its outer tail feathers—so its uppertail looks either unmarked (when closed) or partly striped (when spread).

Cf. Eastern Whip-poor-will.  The Eastern Whip-poor-will has been recorded on Cuba and seems likely to occur regularly in winter.  It is very similar to the Cuban Nightjar, including the pale straps on the back.  If encountered in daylight, the two species would normally be distinguishable by the overall tones of their plumage: Cuban being a cold, blackish-brown, and the Whip-poor-will usually warm-brown.  The male Whip-poor-will typically has much more extensive white on the outer tail feathers, visible mainly on the underside of the tail.

Notes

Polytypic species consisting of two recognized subspecies.  Formerly considered conspecific with Hispaniolan Nightjar (A. ekmani), together known as the Greater Antillean Nightjar (A. cubanensis), but they differ noticeably in vocalizations and tail pattern.
