Great Shearwater in Flight

'Austral' or southern breeders, Great Shearwaters (Ardenna gravis) migrate from breeding islands far to the south in the Atlantic before traveling to the Northern Atlantic to feed. This trip is 6,000 miles each way and, if they're lucky, great shearwaters will complete this round trip every year for a 60-year lifetime. See photos and read more about seabird migration.
