Fulica americana -42-
June 21 Jewel Lake, Tableland Park, Contra Costa Co., Calif.-
Any longer-- at 12:15 p.m. the ♀ went into the S nest, took a look around and
left, swimming down to H 4 - at 12:23 the ♂ went into the nest area also
looked around, then dived to emerge
out in the lake . Now 12:25 he has moved
to near the ♀ where they are both diving.
At 2:05 p.m. a bird crowed at B19.10-
crowed three- almost immediately
a bird (W? ?) came charging over from
near J23 - when at about F20. the
crowing bird splattered over to meet
him at D19 - they immediately went
into paired display and after some
preliminary fooling around they
both reared back on their tails and
lashed at each other with their feet-
they repeated this performance 3 times.
The last time with the W bird almost
on top of the south bird. About the
time the scrapping started the S ♀
"poonked" and came moving up to
aid her mate; she arrived after the
last scrap but joined him in display-
soon they broke off with dabbing
and preening. A little later one of the
S pair was busy bathing - a few minute
later - one of the S pair was perched on
a cat-tail mass near the position of
the original crow. - The nest found
yesterday was revisited today at 3:20 p.m.
very
Still six eggs, and warm - inside
diameter of cup 6½ in., rim 6 in above
water, inside cup about 4 in above water -
