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.
Wedge-rumped Storm-petrel
Wedge-rumped Storm-petrel, 19–21 cm, breeds in enormous colonies in the Galápagos and on islands off Peru. The largest white rump patch of any storm-petrel — nearly triangular, extending to the uppertail coverts. Unlike most storm-petrels, daytime activity at colonies. Planktivore in eastern Pacific upwelling.
