Fulica americana -107-
28 Lake Temescal, Alameda Co., Calif.
In display off the willow point S of the Rocks.
3 were in display first - and then a 4th
splattered in to join them - after the display
broke off they dived and tripped in the
usual separation behavior. - An adult
has moved down along the E side of the
lake bringing 3 or 4 dark gray headed
birds with it - now the SE pair are
again cleaning out the 10 or so
mallards from the channel E of the
Rocks. Both birds are at it - and now
only the ? is working, the ? being
busy feeding on bottom algae! -
The young that was all dark last week
now has a solid white lores and
front of head - this young is actively
begging and feeding with the parent. These
are apparently 2 birds in that
younger brood - now the SE pair
are tattering a ? muddy duck
nearly beside several of their umm.
The SW brood apparently consists of
two young. They are fairly close to the
same age. Both have the white fronts
and both have down covered bodies -
their bills are a light yellowish-gray.
Both as busy feeding them-
selves as well as taking offered
food from their parents. - The
? of the SE pair once this morning
started after several mallards but
stopped when they went up onto
the island - she moved around
in the water nearby "booning"
