The common nighthawk is the only nighthawk occurring over the majority of northern North America. Food availability is likely a key factor in determining which and when areas are suitable for habitation. The common nighthawk is not well adapted to survive in poor conditions, specifically low food availability.
The least nighthawk (Chordeiles pusillus), at 6.3 inches (15–19 cm) and 23 grams (0.81 oz), is the smallest of all Caprimulgiformes, while the Nacunda nighthawk (Chordeiles nacunda) is one of the largest nightjars in the world measuring at 11-13 inches (28–33 cm).
Species that live in the far north, such as the European nightjar or the common nighthawk, migrate southward with the onset of winter. Geolocators placed on European nightjars in southern England found they wintered in the south of the Democratic Republic of the Congo. [9] Other species make shorter migrations. [8]
The eastern whip-poor-will (Antrostomus vociferus; also called "whip-o-will", "whip o' will", etc.) is a medium-sized (22–27 cm or 8.7–10.6 in) bird within the nightjar family, Caprimulgidae, from North America. The whip-poor-will is commonly heard within its range, but less often seen because of its camouflage.
Tyrant flycatchers are passerine birds which occur throughout North and South America. They superficially resemble the Old World flycatchers, but are more robust and have stronger bills. They do not have the sophisticated vocal capabilities of the songbirds. Most, but not all, are rather plain. As the name implies, most are insectivorous.

The storm-petrels are the smallest seabirds, relatives of the petrels, feeding on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like. Until 2018, these three species were included with the other storm-petrels in family Hydrobatidae.
