About the Markham's Storm Petrel

Markham's storm petrel is a seabird native to the Pacific Ocean around Peru, Chile, and Ecuador. The species is named after British explorer Albert Hastings Markham, who collected the specimen on which the scientific description was based. It is a large and slender storm petrel, with a wingspan between 49 and 54 cm. Its plumage is black to sooty brown with a grayish bar that runs diagonally across the upper side of the wings. A member of the family Hydrobatidae, the northern storm petrels, the species is similar to the black storm petrel, from which it can be hard to distinguish.
