Antarctic Petrel

Thalassoica antarctica

Least Concern

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

Spotted something wrong?

The Antarctic petrel is a seabird boldly patterned in brown and white, endemic to Antarctic waters. It breeds in colonies on cliffs and nunataks on the continent, some of them more than two hundred kilometres from the coast, and feeds on krill, squid and fish at the ice edge. A single colony in the Svarthamaren mountains, in Queen Maud Land, holds hundreds of thousands of pairs.

Fun facts

  • The Svarthamaren colony, deep in the Antarctic interior, holds more than 200,000 pairs 200 kilometres from the nearest sea: the adults make round trips of more than four hundred kilometres to bring food to a single chick.
  • Like other petrels, it defends itself by spitting a foul-smelling stomach oil that mats the attacker's plumage, which is especially dangerous for other seabirds, since they can lose their waterproofing.
