About These Birds
Ashy Storm-petrel
Ashy Storm-petrel, 19–21 cm, is restricted to the California Current of the eastern Pacific; breeding on Channel Islands and the Farallon Islands. Entirely ashy brown without white rump — uncommon among storm-petrels. Endangered; less than 10,000 individuals; threatened by light pollution and introduced predators.
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.
