(5) Nov.4,1966 Below Vista Pt., Marin Co., Calif. Bilo Arvey Journal be within range when he comes up so I can see how he's oriented. He's up after 46 seconds, facing Berkeley again; he appears not to have anything. He's looking around, around, still facing towards after 29 seconds on the surface. Berkeley, dove/ See several groups of cormorants flying out of the Bay now; perhaps there's a diurnal pattern of movements in and out of the Bay which I hope I can detect tonight. There's a Western Gull out there by another cormorant that just dove, looking for a handout no doubt. The cormorant I'm timing just came up after 55 seconds, nothing in his bill. He hadn't travelled more than 15 or 20 ft. from where he went down, so possibly it's a more vertical dive than a hori- zontal dive. I'm almost sure that's what it is. Dove again after 28 seconds on the surface. The cormorant that was around the gull came up and the gull hasn't made any move to travel overf to him, so apparently he's not actively mooching right now. See alot of cormorant activity out further now. Several groups of cormorants out there. I missed the end of the cormorants dive. I'll watch the cormorant near the gull; he's approximately 20 ft. from the gull; a Brandts. He's moving away from the gull, dove. He came up with a fish after 58 seconds. Just dove right in front of the gull after 10 seconds on the surface. He's up again.
