Résumé :	The Short-tailed Shearwater Ardenna tenuirostris is an abundant species of the Pacific Ocean.We reviewed records for the Indian and Atlantic Oceans and suggest that a regular pattern of movement in these oceans is hitherto unrecognised. It follows that the vagrancy potential of Short-tailed Shearwater to the North Atlantic probably is greater than suggested by the few documented records. Short-tailed may have been overlooked or confused with the similar looking Sooty Shearwater A. grisea and, in the northeast Atlantic, dark-plumaged Balearic Shearwater Puffinus mauretanicus. Criteria for the separation of these three species at sea are presented in a bid to establish a clearer picture of the status of Short-tailed Shearwater in the North Atlantic. Separation of Short-tailed from Sooty Shearwater builds on existing criteria; characters for separation from dark-plumaged Balearic Shearwater are new.
