P. DeBenedetti 1964 Aug 30 Monterey Bay off Monterey, Calif. (good trip) 65,000+ Sooty Sheawater - encountered about 7 mil out, but the majority were seen 8-15+ miles out, thus they gradually diminished in #s until they were only 2-5/minute could be seen as p), at about ½ the south bound leg. We again picked up #s c. 1 3/4 miles off Pt. Pinos, and saw them at 20-100 birds/minute until about 7 miles from the pier. On the way out, birds were first seen streaming by at 2-500/ minute until c. 8-8 ½ miles, then for the next hour or so we encounter groups of 2-500 on the waters with flocks of 1000-5000 almost constantly in sight. The birds on the water were mostly resting, but a few were seen to dive - mostly solitary birds. Flocks seemed not to move with much organization except that the general pattern of movement was north along the bay. No bird were seen diving. Although a "Sooty" zone was clearly defined on the east side, it gradually disappeared on the west side. Birds did not generally allow approach to within c. 200 feet, and took off into the wind, then circled back with the wind when approached. By far the commonest species; estimate: 6000+36000+18009 out, 3000 in.
