Too often, humans seem to bring native bird populations nothing but misery.
Years of clearing native forest has removed much of their habitat, while in remnant bush areas introduced predators attack them daily.
But New Zealand's beleaguered native birds have some human friends in Auckland including about 600 "Ark In the Park" volunteers.
Under this scheme, volunteers put in 9000 hours a year to boost conservation in the Waitakere Ranges Regional Park.
Since Ark in the Park began 12 years ago, volunteers have reduced pests populations in 2100ha of bush, destroying wasp nests, laying bait lines for possums and trapping rats and stoats. They maintain tracks and educate park users, for example, on disinfecting footwear to reduce spread of kauri die-back disease.
