Black stilt
As of 2021 there were about 170 of these birds alive in the wild. In 1981, there were only 23 birds. There are fewer of them because of invasive species, animals that humans brought to New Zealand. Cats and ferrets kill many stilts, chicks, and eggs. Human beings also change the places where the birds like to live. Human beings using the seashore for work or fun can scare the adult birds away from the nests. They can accidentally kill the chicks or eggs.
