Status
The southerly subspecies, is now only present on Stewart Island at the southern end of South Island and in 1990 its numbers had reduced to about 62 individual birds. Conservation measures were put in place involving the poisoning of feral cats and the population has gradually risen, with about 250 individuals being recorded in 2005. The northerly subspecies has a wider range at the northerly end of the North Island and its population was about 1300 in 1989. It had recovered to about 1700 individuals by 2004 but only as a result of intensive management. The IUCN rates this bird as "Endangered".Reproduction
Parents lay eggs in the spring and summer. They nest on beaches above the high tide mark, and the nest is just a shallow hole dug in the ground, not made of twigs like a nest in a tree. The chicks hatch about 28 days after the eggs have been laid. Because the nests are on the ground, chicks can walk the day they hatch and can usually fly within 6–8 weeks.References:
