Includes Scopoli's Shearwater
C. d. diomedea (Scopoli's Shearwater): Length 45-52 cm, wingspan 112-122 cm, weight 560-730 g.
Variation: the two subspecies differ slightly in plumage, with C. d. diomedea showing a little less black in the hand of the underwing due to white inner webs on the primaries, slightly smaller bill which is a little paler, overall slightly paler; the lesser overall size is not noticeable in the field. The average difference between these two forms is difficult to use because of much individual variation. More identification discussion in reference 6.
