Scripps's Murrelet

Synthliboramphus scrippsi

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

Scripps's murrelet is a small black-and-white auk that breeds in crevices and under bushes on a few islands off California and Baja California. It was split from the Guadalupe murrelet as a species of its own in 2012. Its chicks do something astonishing: they leave the nest two days after hatching, throw themselves into the sea from the cliff and finish growing up on the open ocean with their parents.

Fun facts

  • Its chicks leave the nest two days after hatching: they run down to the cliff edge at night, throw themselves into the sea and swim out with their parents, which go on raising them on the open ocean for weeks.
  • The eradication of rats on Anacapa Island, in California, multiplied its breeding success immediately and is one of the best-documented cases of island restoration in North America.
  • It was recognised as a species of its own in 2012, when it was separated from the Guadalupe murrelet, with which it had been lumped for decades.
