Antillean Nighthawk
Chordeiles gundlachii
The adults are dark with brown, grey and white patterning on the upperparts and breast; the long wings are black and show a white bar in flight. The tail is dark with white barring; the underparts are white with black bars. The adult male has a white throat; the female has a light brown throat. The most distinguishing characteristic to determine its identity from its closest relative the common nighthawk are the contrasting pale tertials near the back of the wings of a sitting bird. There are two color morphs, a gray and a rufous type. Voice: The call is a short pikadik usually heard overhead. The common nighthawk occasionally will make a similar call, but it is not as consistent. In the Dominican Republic, the bird is called querebebé; in Puerto Rico, the bird is called querequequé. Both are onomatopoeic terms which originate in Taíno.

Band-winged Nightjar
Systellura longirostris
Over its large range, there are significant variations in its morphology, but, as suggested by its common name, it always has a distinctive band in the wing (best visible in flight), which is white in the male and buff in the female. This nightjar has a length that varies from 20 to 27 cm (for Ecuador, 21.5 to 23 cm). The iris, bill, legs, and feet vary from brown to blackish brown. On the upper side, a greyish-brown, blackish-brown, brownish-orange, pale yellowish-brown, and greyish-white coloration can be distinguished. The rear of the neck is from a brownish orange to a yellowish brown. Voice: The species has a variety of calls. The territorial tone is a high-sharp whistle, seeeeert sweeeert seeeet, constantly repeated every 1 to 3 seconds. Whistles can be heard at dusk or dawn. The flight whistle is usually heard during the breeding season as a high cheet. Females when flushed produce a nasal sound like tchree-ee.
