The Guadalupe Murrelet breeds on a small number of islands off the Baja Peninsula in Mexico and may also breed off the coast of California. In winter it can occur off the coast of Baja California north to British Columbia. The global population of this bird is estimated to be around 7,500 individuals, and it lives in coastal waters and along sea cliffs. This species is threatened by invasive mammalian predators on its breeding grounds, pollution, and other factors, and has been given an IUCN conservation rating of Endangered.

INTERESTING FACTS

  • A group of auks has many collective nouns, including a "colony", "loomery", and "raft" of auks.
  • On Santa Barbara Island, deer mice destroyed an average of 42% of eggs laid every year and were sometimes observed killing untended chicks.
  • The major threat to the survival of this species is depredation of eggs and young by introduced mammals on its nesting islands. Feral cats, which may also kill incubating adults, have been responsible for eradicating murrelets from a number of islands.
