About These Birds

Guadalupe Storm-petrel

Guadalupe Storm-petrel, 22–23 cm, is Critically Endangered — possibly extinct; no confirmed sightings since the 1930s when cats eliminated the colony on Guadalupe Island. Large, all-dark storm-petrel very similar to Black Storm-petrel. Status uncertain; intensive searches have not relocated any individuals.

Least Storm-petrel

World's smallest seabird at 13–15 cm. Sooty-black with white rump; short rounded wings. Breeds Baja California islands; ranges offshore in eastern Pacific to Ecuador. Feeds on zooplankton and small fish by pattering on the surface. Nocturnal at breeding colonies; Near Threatened.
