The mohua, or yellowhead, has been crowned Bird of the Year in Forest & Bird's ninth annual poll.
The mohua won 2473 votes in total, out of 12,925 votes cast, followed by the ruru with 1716 and the southern rockhopper penguin with 1524.
Forest & Bird's advocacy manager Kevin Hackwell said the mohua had been one of the most abundant forest birds in the South Island and Stewart Island, but is now on the endangered species list, due to habitat loss, predation and climate change.
"The mohua is a climate change canary,'' he said.
"Populations have suffered recently because a series of warm summers have caused beech trees to mast (produce large volumes of seeds) more frequently. In mast years, you see a spike in rat numbers, which eat the beech seed. This in turn causes a spike in stoat numbers, which eat the rats. Once the rats are eaten, the stoats go looking for alternative food, such as mohua, and other native birds''.
