A small, pelagic alcid of the California Current, the Scripps's Murrelet is a secretive seabird known for its unique 'at-sea' chick-rearing strategy. It was formerly classified as a subspecies of Xantus's Murrelet before being recognized as a distinct species in 2012.

Field notes

  • Chicks are highly precocial, leaving the nest to swim into the open ocean with their parents just two nights after hatching.
  • Unlike most seabirds, parents do not feed their young at the nest; all chick growth occurs entirely at sea.
  • Adults are strictly nocturnal at breeding colonies, arriving and departing under the cover of darkness to avoid avian predators.
  • The species is a 'California Current endemic,' largely restricted to the nutrient-rich upwelling zones of the Pacific coast.
  • They are listed as a threatened species in California due to their small breeding range and high vulnerability to oil spills and invasive island predators.
Habitat
Pelagic waters and steep, rocky offshore islands with dense maritime scrub or deep crevices.
Range
Breeds on islands off Southern California and Baja California; disperses north to British Columbia during the non-breeding season.
