General

Little Tern: Small white tern with black cap and white front. White-gray on back and upper wings. Outer three primaries black-gray. Medium-length, pointed, orange-yellow bill with black tip. Long, pointed wings. Medium, forked tail. Short, orange-yellow legs and feet. Sexes similar. Winter adult has less black on head, black bill, and duller legs. Juvenile like winter adult but more black in wings. Forages for small fish by hovering above water in lagoons, and plunge-diving for prey.

Breeding and Nesting

Little Tern: Two to three cream-colored eggs with black-brown spots and blotches are laid in a shallow scrape on sandy ground. The nest is often placed near water but above the high-tide line. Incubation is carried out by both sexes for 21 to 30 days. This species usually nests in small colonies.

Foraging and Feeding

Little Tern: Feeds on small fish, insects, and other small marine creatures. It catches food by hovering above the water and then diving below the surface to snatch prey with its bill. This tern species often feeds in very shallow water at the edge of a lagoon, in channels, or at the edge of an advancing tideline.

Vocalization

Little Tern: Colonies produce a lot of chattering "kirrikikki kirrikikki." Nesting pairs emit squeaky calls.

Similar Species
