Black-fronted Tern

Overview

The black-fronted tern (Chlidonias albostriatus) is a medium-small tern endemic to New Zealand. It is classified as endangered globally and nationally due to its small and declining population.

Identification

• Medium-small bird measuring 28–30 cm in length with a 65–72 cm wingspan.
• Dark grey upper body and light grey underparts with a white rump and a distinctive black cap.
• Short orange bills and short orange legs.
• In the non-breeding season, the black cap recedes and becomes flecked with white.

Habitat

Found in coastal habitats from the southern tip of the North Island to the eastern South Island and Stewart Island. Breeding is restricted to the eastern South Island, where they form colonies on braided river islands.

Diet

Forages for insects and small fish in coastal areas, including estuaries, harbours, and farmland up to 3 km inland. Will forage up to 10 km out to sea, particularly in calm weather, and also forages for earthworms and grubs in freshly turned soil.
