Breeding.<\/em><\/strong>\u00a0 Nests in steep terrain in the highlands of Santa Cruz, Santiago, Floreana, San Crist\u00f3bal, and Isabela islands, mostly at elevations above 300 m in burrows, lava tubes, caves, and sinkholes.\u00a0 Breeding occurs year-round, but various local subpopulations breed on differing timetables.<\/p>

Surveys detected a dramatic decline in the 1980s, from approximately 27,000 nesting pairs in 1980 down to around 3,500 pairs in 1985.\u00a0 Since then the population may have stabilized, as it was estimated in the range of 4,500-5,000 pairs in 2008.<\/p>

Nonbreeding.<\/em><\/strong>\u00a0 Forages in waters around the Gal\u00e1pagos and in the tropical waters east, west, north, and south of the archipelago, including waters just offshore from northwestern Peru and southwestern Ecuador.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
