White fronted tern and fledgling - photographer Dr Kerry RodgersThe White Fronted Tern is the most common tern in New Zealand. It has a long black bill and short black legs. The head is capped in black to below the eye, leaving a white area above the bill. The upper parts and upper wings are a pearly grey/white and the neck, underparts and underwings are white. The call is a high pitched 'siet'.

Breeding takes place between October and January in large colonies on rocky cliffs and offshore islands. The nest is a shallow, unlined hollow, in which one egg is normally laid, though clutches can number as many as three eggs. Both adults incubate for around 24 days and brood the chick (normally only one is raised) for a few days after hatching. The chick fledges at around 29-35 days and continues to be fed by its parents for about three months after fledging.

White fronted tern - photographer: Simon FordhamWhite fronted terns feed in large flocks on small fish by plunge diving. Shoals of smelt and pilchards which have been driven to the surface by larger fish are easily caught by the terns.

On Tiritiri Matangi they are most often seen on and around the wharf, though they have bred regularly on the eastern side of the Island. Like many terns, they change their breeding sites from time to time.
