Antillean Nighthawk

Chordeiles gundlachii

A common nesting bird on islands of the Caribbean, this nighthawk enters our area only in southern Florida. When it was first discovered there in 1941 it was considered to be only a subspecies of the Common Nighthawk, as it looks very similar; however, its voice is different. Where Antillean and Common nighthawks meet on the Florida Keys, they appear to compete and to defend territories against each other.
Conservation status Probably increased in Florida through the 1970s as land on the Keys was being cleared, now declining again as land is developed.
Family Nightjars
Habitat Open areas. In Florida this nighthawk is concentrated around undeveloped open ground, such as airports vacant lots, fields. In the Caribbean it inhabits semi-open terrain including open woods, fields, farmland.
