Fulica americana -125-
lot 33 Lake Temescal, 420 ft., Oakland, Alameda Co., Calif.
diving and feeding in the general area. At 2:25 p.m.
cam able to count 17 coots on the lake. At 2:28 pm.
a ♂ from the S pair and a ♀ from the SW pair together,
charging about 20 to 30 feet apart along parallel
paths, drove 4+ immature birds out of the SEnd area.
This aroused crowing on the part of a NE bird,
and one♂ was seen moving down so if to meet
the challenge. A smaller adult, which I took
to be the SW♀ followed her mate, and he turned
to meet her and they both came together in
a charging position, dipping their bills as they
passed and then immediately holding their
heads high; In the several succeeding minutes
two birds, I believe the SW pair, chased a
total of 8 ♂ the birds, mostly immatures
into the NE area - a moment later one of
the NE adults went to work chasing
at least 1 immature ? out. - Earlier I had
an opportunity to watch a coot take a bath.
I had not seen this g before, and was not
surprised to see it accomplished the same
way a duck takes a both, with much
splashing and throwing of water with the
wings.
lot 30 Lake Merritt, ft., Oakland Alameda Co., Calif.
Fed a group of about 8 to 10 coots on the
ground by the seats at the duck refuge.
Two larger birds, both giving the ♂ type
call maintained dominance over the flock,
only occasionally pecking at one another, but
regularly assailing any other of the smaller
birds coming within range. Ducks,
especially a ♀ Pintail, blundered their
