VOLUME 59 (2005) NUMBER 4 677 Storm-Petrel and Manx Shearwater (Lee Wilson's Storm Petrel 1995, Keith and Keith 2003).

This species'distribution in the North At- lantic duringthe nonbreedingseason has typicallybeen mapped as extending no far- therwest than ca. 40ø W (e.g.,Cramp and Simmons 1977, Brooke 1990, Carboneras 1992). It is now clear that it extendsmuch fartherto the west,at leastduring north- boundmigration. 5 The informationcollected during the presentstudy also raises several questions. . I. AlthoughSooty Shearwaters migrate in large numbers into the Northern Atlantic in Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec spring,they were observedin very small numberscompared to GreaterShearwaters.
