FULICA AMERICANA

Mar 22 Lake Temescal, 420 ft., Alameda Co., Calif.
egg nest. (ill see dates)
-> Jewel Lake, 510 ft., Contra Costa Co., Calif.
A nest with 4 eggs found at F 25.7.
Eggs cool, marked 1, 2, 3, 4. Nest
big bulky, composed almost entirely of
deal cat tails - or I should say,
completely composed of deal cat tails.
While this nest is not close to the open part of the lake, the beaten up
nature of the cat-tails puts it in a
fairly open position, so it is close
to open water. The same faces the
open water to the NE. It has a
very deep cup. There seems to be
only 4 birds on the lake today,
plus two geese and a pair of Golden-
eyes. Could find no nest in the
area I 18 south to I 6, or from
c 6, thru to A 17. But the S pair
watched me closely all the way
around, showed most concern
when I was near H 14. I did not
get out to the point at F 9. Several
times the S pair were billing,
but the N pair were not close
together. One N bird was near
6-17, the other at the corner N of the
island.
Mar 24 Aquatic Park, Berkeley, Alameda Co., Calif.
1 coot seen near boathouse, slightly
swollen shield. 3 coots in area
immediately north of refuge area.
