Cogswell 1949 2 Jelmarus glacialis July 20 Just N. of Pt. Pinos to 9 mi. W. & slightly south of it, Monterey co., Calif. an estimated 15-20 seen at various points, some on the water & of the same worn down color as those in the Bay, others in apparent good plumage & flying well, all the latter were in typical dark phase or the mottled dark phase seen in winter; but several more very white birds were among those on the water. Several times I compared the flight of the Fulmar with that of Puffinus griseus & noted the following: Fulmar vs. Sooty Shearwater -frequency of beat series about the same (in full plumage -freq. of beats within series less greater depth of stroke about the same height on turns more variable tends always gliding much to rise to ht. speed slower much carriage head: large L with small f with horizontal horizontal. nov. 20 (same locality) - about 30 seen, all of them fully active, flying well, and taking off with only a moderate run. 2 of those seen were in light phase plumage, the others in various degrees of dark mottling to full "dark" phase. another difference between Fulmar & Sooty Shearwater is that the former never holds wings in nearly closed position while running over the surface as does the latter.
