The Antillean Nighthawk and the Sooty Tern are easily distinguished by their habitats and behaviors. The nighthawk is a land-based bird often seen in open areas at dusk, while the tern is a seabird that rarely lands outside of breeding colonies. Their plumage and flight patterns are also distinct.

Habitat is the most reliable field mark: nighthawks are terrestrial, while terns are marine. Plumage differences are also clear: nighthawks are mottled, terns are black and white. Observe behavior: nighthawks are active at dusk over land, terns are almost always seen in flight over the ocean.

The Antillean Nighthawk typically has mottled brown and gray plumage, providing camouflage against the ground. In contrast, the Sooty Tern has a striking black and white appearance, with a black cap and back and white underparts.

The Antillean Nighthawk is known for its crepuscular activity, often seen flying low over open areas at dusk. The Sooty Tern, however, is almost exclusively aerial, spending years at sea without landing, except during breeding.

Antillean Nighthawks are found in open, terrestrial environments, while Sooty Terns inhabit tropical and subtropical oceans, nesting on remote islands.
