Pt. Lobos.
9:30 AM. Arrived at Colony. Overcast w/ low clouds - Fog.
Temperature 60-65°. Observing Bird Island from about 150yd.
945. Sun beginning to break through. We have 3 general
nesting groups of Brandt's Cormorants under observation.
There is a colony at the far Southern part of the wave cut
terrace which will be number 1. It appears to have many
more nests hidden from view but I can observe about
30 nests. The center (number * 2) Colony has 100 + nests
which appear to be under different stages of construction,
rebuilding and incubation. Colony is N. side of rock, on
sloping rocky part beneath the terrace; (number 3) appears
to be as extensive with perhaps 100 nests. Cormorant
activity is rather slow right now, may pick up as the sun
appears.
Some cormorants can be seen in various courtship
displays, even though the birds in question are associated
w/ nests. Many appear w/ bright blue/gular pouches.
About the nests are seen Leaman's gulls, adults and juveniles,
and when we first came we saw a large number of this
species roosting w/ pelicans near the parking lot. Some may
be seen walking among the cormorant nests without causing
great disturbances. Brown Pelicans are very abundant in
many plumage stages; these do not walk among cormorant
nests and there is a sharp dividing line between nesting
pelicans and cormorant nests. Also common here are western
gulls, though not numerous at present. At least one
