Sterna nereis davisae Mathews & Iredale, 1913 |
The New Zealand Fairy Tern (Sterna nereis davisae) is a small tern which breeds on the lower half of the Northland Peninsula of the North Island of New Zealand. It is a subspecies of the Fairy Tern.
Breeding is limited to three regular sites: Waipu, Te Arai, and the South Kaipara Head. The wintering range of the birds extends over the Kaipara Harbour. Outside of the breeding season fairy terns form flocks on the harbour, often around Tapora.
The total population as of 2005 is 35 to 40 individuals including 13 breeding pairs and the species is critically endangered. It nests on sand and shell banks just above high tide mark and nesting is highly vulnerable to introduced predators, domestic animals, storms, very high tides and disturbance by humans on foot and in vehicles on the beach. The bird is further threatened by a proposed residential subdivision at Te Arai, next to one of its prime breeding sites.
