About These Birds
Ringed Storm-petrel
Ringed Storm-petrel, 21–23 cm, is an extremely poorly known species with a highly restricted range over the Humboldt Current off Peru and Chile. White underparts with a distinctive dark breast band — giving the 'ringed' appearance. Breeding grounds unknown until recently; likely nests in Atacama Desert.
Black Storm-petrel
Black Storm-petrel, 22–23 cm, is the largest entirely dark storm-petrel of the eastern Pacific, breeding on San Benito Islands and Coronado Islands off Baja California. Deeply forked tail; languid, loping flight distinctive among storm-petrels. Planktivore and piscivore. Near Threatened; small breeding population.
