Worldwide Species Action Plans
The New Zealand fairy tern (Sterna nereis davisae) is New Zealand?s rarestindigenous breeding bird. It is a morphologically distinct, geographically andgenetically isolated, endemic subspecies of an Australasian species, which consistsof two other recognised subspecies: S. n. nereis in Australia and S. n. exsul inNew Caledonia. The population is estimated to number 35 to 40 individuals andnow only breeds at four breeding sites in the North Island. It is threatened byintroduced mammalian predators, disturbance and habitat modification. This planpresents a revised goal and the objectives required to continue recovery of theNew Zealand fairy tern. Actions in this plan focus on the continued protectionof the breeding pairs and their progeny in situ. Research is required on criticalpopulation demographics.
