Cogswell 1949 Puffinus griseus July 4 - Pt. Dinos, Monterey Co., Calif. The shearwater flight offshore here this evening was the best yet — insofar as observation was concerned. Those recorded in my journal on June 17 were most probably this species as it has been common at the "mouth" of Monterey Bay ever since, on several dates we have watched them from Cabrillo Pt. (Hopkins Marine Sta.) Pt. Aulon (Tavern's Pt., foot of 17th St., Pacific Grove) and from here. On June 25 one came close enough to shore here where I saw the pale gray wing-lining areas. Largest numbers were estimated on June 26 at 300 off Pescadero Pt. in early A.M., and I think fully as many are here this P.M., many of them coming close enough for specific identifica- tification [see also P. opisthomelas & D. bulleri]. They seem to be closest to shore in early A.M. and just before dark. At mid-day they are still in sight, coursing up and down about where the deep ocean swells break up upon entering Monterey Bay — but they are then too far out for identification. Some days they are not in sight at all from the shore at mid-day. The movement, if watched for only a short time
