Newell's Shearwater

Puffinus newelli

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

Newell's shearwater is a seabird endemic to Hawaii that breeds in burrows dug on mountain slopes in the interior of the islands, above all on Kauai, and feeds on the open sea. Its population has fallen by more than ninety per cent since the 1970s. The main causes are predation by cats and rats and, above all, the disorientation of fledglings by artificial lights.

Fun facts

  • The fledglings that leave the nest at night are disoriented by artificial lights, circle until they are exhausted and fall to the ground on roads and in car parks: on Kauai there is a programme that collects hundreds of downed birds every autumn to return them to the sea.
  • Its population has fallen by more than ninety per cent since the 1970s, and reducing light pollution on the island is the most effective conservation measure identified so far.
  • It nests above a thousand metres on fern-covered slopes in the interior of Kauai, and makes round trips of tens of kilometres to the ocean every night.
