'''Habitat:''' Southern Hemisphere; they are long-distance migrants, following a circular route, travelling north up the western side of the Pacific and Atlantic Oceans at the end of the nesting season in March-May, reaching sub Arctic waters in June-July where they cross from west to east, then returning south down the eastern side of the oceans in September-October, reaching to the breeding colonies in November. They do not migrate as a flock, but rather as single individuals, associating only opportunistically. | '''Habitat:''' Southern Hemisphere; they are long-distance migrants, following a circular route, travelling north up the western side of the Pacific and Atlantic Oceans at the end of the nesting season in March-May, reaching sub Arctic waters in June-July where they cross from west to east, then returning south down the eastern side of the oceans in September-October, reaching to the breeding colonies in November.

| - | '''Status:''' | + | '''Status:''' Near Threatened. '''Global Population:''' 20,000,000 mature individuals. Along with the Short-tailed Shearwater, the Sooty Shearwater is one of the most numerous shearwaters. The total population is probably in the tens of millions. In recent years however, numbers off parts of the West Coast have declined significantly. It is speculated that this decline may be as a result of the rise in sea surface temperatures. It is presently classified as Near Threatened by the IUCN. |
'''Diet:''' Fish and squid. They can dive up to 220 feet (68 m) underwater for food, but more commonly take surface food, in particular often following whales to catch fish disturbed by them or fishing boats to take fish scraps thrown overboard. | '''Diet:''' Fish and squid.
