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. See references below for a discussion of the differences between the two. | 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.

Antillean Nighthawk is known from the [[Greater Antilles]], the [[Bahamas]] and Southern [[Florida]], especially the Keys and [[Tortuga]]. However, recently they have been demonstrated to breed in e.g., [[Guadeloupe]] of the [[Lesser Antilles]]. The Antillean Nighthawk migrates out of its breeding range after raising its young. It still remains unknown where the birds spend the winter ([[South America]] is assumed to be the place). | Antillean Nighthawk is known from the [[Greater Antilles]], the [[Bahamas]] and Southern [[Florida]], especially the Keys and [[Tortuga]].

Similar Species
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. See references below for a discussion of the differences between the two.
Distribution
Antillean Nighthawk is known from the Greater Antilles, the Bahamas and Southern Florida, especially the Keys and Tortuga. However, recently they have been demonstrated to breed in e.g., Guadeloupe of the Lesser Antilles. The Antillean Nighthawk migrates out of its breeding range after raising its young. It still remains unknown where the birds spend the winter (South America is assumed to be the place).
Taxonomy
The birds in Florida and the Bahamas are supposed to be a different subspecies (vicinus) from the rest of the region
The Antillean Nighthawk was until recently thought to be the same species as Common nighthawk.[2]
Subspecies[1]
- C. g. vicinus:
- C. g. gundlachii:
- Cuba, Isle of Pines, Jamaica, Hispaniola, Puerto Rico, Virgin Islands
Habitat
Mainly belong in open country. Seashore with sparse vegetation and airfields. Wetlands
Behaviour
Diet
They hawk for flying insects
Breeding
They lay two eggs on the ground. Incubation (by the female) takes around 20 days and fledging another 20.
Vocalisation
Call: a short pik-adik usually heard overhead. (The Common Nighthawk makes a similar call, but it is not as consistent.)
