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.
