Fulica americana -60-
July 10 Jewel Lake Tilden Park Contra Costa Co. Calif.
Immatues gathered around the injured
bird, it seemed to be bleeding at the
mouth but can wiggle its tail and move
its wings. Don't know where it was
hit- sure hope it pulls out okay.
At the moment G, 0/5, R, R15, and one
unmarked bird are feeding at F+G-8.
A moment ago the unmarked bird
made a pass at the tag on R15 but
was unable to get close enough to
touch them. The unmarked adult
from the S end has been seen this
afternoon too. About 4 p.m.
The N♀ was with 4 young at
526 and then about 4:20 p.m.
The N♀ was chasing all of
the immatues out of the area
at G15-16+17. A moment later 4
young appeared there and then slowly
drifted northwest towards the
island from the boat. Those
two flying immatures that are
unmarked have been the leaders in
that N brood- probably the oldest- and
consistently do the first to fly
when alerted- by 5:05 p.m. The
injured bird was dead. It is one
of the two smallest birds in the
S brood, I'm sure sorry to lose it.
Guess I'd better skin it out. As
I worked over to get it, all the
birds previously feeding in that area
worked down the cat-tails on the
west side and onto the open water
