Migratory Seabirds: A Slideshow

All seabirds spend a significant part of their lives at sea, and many experience many parts of the world's ocean as they migrate around the globe every year. Some seabirds travel very far distances, like the Sooty Shearwater, which GPS trackers have followed for more than 40,000 miles, figure-eighting across the Pacific Ocean, within just a year. Some, like Audubon's shearwater, stay closer to home, circling a range of just a few hundred miles near their breeding grounds in search of food. See photos and read more about seabird migration.

An 'austral' or southern breeder, Great Shearwaters (Ardenna gravis) migrate from breeding islands far to the south in the Atlantic before traveling to the Northern Atlantic to feed.
