June 27 Jewel Lake, 5/8 ft. Contra Costa Co., Calif.-
of the ? is not got pecked. Both of these
immatures are very nearly the size of
the adult. In fact one looks to be
fully as large as the adult or
larger. 2:41 p.m. The O came up to
the nest from the S, with a bill
full of long dried cat-tail leaves.
As he came up the ramp I got
down off the nest and left to the S. A
few low "puts" were heard. The O
spent about 1 minute preening
etc. before settling on the nest.
To 3:48 p.m. There was not a
second shift. The incubation pattern
is different here, but just what the
difference is I don't know, except
longer intervals. 4:00 p.m. No
defense of nest when I waded to it.
The eggs all very warm, but #3 is
missing. No adult even in the
vicinity. A couple of moments later
as I moved out to pull some cat-tails,
the O got out of the cat-tails about
10 feet south and proceeded to churn
and "pulque" and generally carry on.
Four gray immatures moved N
along the cat-tails on the E side
and he worked over as if to join them.
At 4:30 a bird might be on the
nest. I'm not sure, 5 immatures are
feeding at on the clear water of the N
pool, what clear water is left.
