Markham's storm petrel (Hydrobates markhami) is a seabird native to the Pacific Ocean around Peru, Chile, and Ecuador. It is a large and slender storm petrel; its plumage is black to sooty brown with a grayish bar that runs diagonally across the upper side of the wings. A colonial breeder, the species nests in natural cavities in salt crusts in northern Chile and Peru; 95 percent of the known colonies are found in the Atacama Desert. Pairs produce one egg per season, which is laid on bare ground without any nesting material. Parents will attend their brood only at night, returning to the sea before dawn. The diet of Markham's storm petrel consists mainly of fish, cephalopods and crustaceans. Despite its relatively large population, the species is in decline and listed as near threatened. Primary threats are habitat destruction and light pollution, which attracts or disorients fledglings on their first flight to the sea. (Full article...)
