The Tristram’s Storm-petrel (Oceanodroma tristrami) is a species of seabird in the storm-petrel family Hydrobatidae.
The species’ common and scientific name is derived from the English clergyman Henry Baker Tristram, although the species is also known as the Sooty Storm-petrel.
Distribution / Breeding
The Tristram’s Storm-petrel has a distribution across the north Pacific Ocean, predominately in tropical seas.
The species is colonial, nesting in the Northwest Hawaiian Islands, and in several small islands south of Japan, including the Bonin Islands and Izu. Colonies are attended nocturnally, and the species breeds during the winter.
At sea the species is pelagic (open sea), feeding on squid and fish.
The Tristram’s Storm-petrel is considered near-threatened. All of its breeding colonies in Hawaii are protected areas, but the species has undergone declines in the past due to introduced rats on Torishima Island.
The Tristram’s Storm-petrel has long angular wings and is 24 cm long. The plumage is all over dark with a slightly pale rump and a pale grey bar on the upperwing.
