Manx shearwaters Puffinus puffinus breeding in the western Atlantic follow a different migration route from their eastern Atlantic conspecifics
Manx Shearwaters are transequatorial migrants, and most of the world's population breeds in Britain and winters off the Patagonian Shelf in the western South Atlantic. The migration route of British birds follows a well-known clockwise movement between the North and South Atlantic, taking advan...
