Yelkouan Shearwater

Puffinus yelkouan

Vulnerable

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

Spotted something wrong?

The Yelkouan shearwater is a seabird endemic to the Mediterranean that spends almost its whole life on the open sea and comes ashore only at night to breed, in crevices and burrows on islets and cliffs. It flies low over the waves on stiff wings, alternating glides with bursts of rapid wingbeats. Its greatest threats are rats and cats introduced onto the breeding islands and accidental capture on longlines.

Fun facts

  • It comes in to the colony only at night and in the deepest darkness: it avoids full-moon nights because yellow-legged gulls and raptors are waiting for it along the coast.
  • Rats introduced onto the islets are its greatest threat on land: eradicating rats from a handful of Mediterranean islands has been enough to multiply the breeding success of entire colonies.
