Ancient Murrelet

Synthliboramphus antiquus

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The ancient murrelet is an auk of the North Pacific with a black head, a grey back and fine white feathers above the eyes that give it a grey-haired look, which is where its name comes from. It breeds in burrows dug beneath the forest on North Pacific islands, and its chicks leave the nest at two or three days old to join their parents at sea.

Fun facts

  • Its chicks leave the burrow two or three days after hatching and run down through the forest to the sea, guided by their parents calling from the water: a night-time journey of hundreds of metres for a chick a few days old.
  • Its name refers to the fine white feathers on its head, which recall the grey hair of an older person.
  • Introduced rats and raccoons have wiped out its colonies on several North Pacific islands, and its recovery on Haida Gwaii after the eradications is a benchmark case in Canada.
