Fulica americana -82-
July 80 Lake Towsend Alameda Co. Calif.
seemed to keep their distance from the
one adult coot - and when another coot
came out from to S end they all
moved - one duck that did not
move was charged, then splattered
at - the duck flew a few feet - the
coot churning when it settled back
onto the water - territory seems to
be in effect here - one adult after
chasing the mallards moved on
towards another adult - this
bird retreating to its brood near
the E side of the lake - after the
N bird beat its retreat the other
bird turned S. The N bird
was greeted by cries of begging
as it came in near the place
where its 5 young were busily
feeding in a mass of Potamogeton.
Although the young made the
begging screeches, they did not
rush over to meet the approaching
parent - There are 3 broods on
the lake - the 3rd one consisting
of birds that are about 3 weeks
old - they still have natal down
but have lost all plume feathers.
their bills are no longer bright
red but rather a dull brownish
or orange color. 2 of these young
were seen, belonging to the B+Q
which was responsible for
chasing the mallards and the
other coot out of the area just
