Fulica americana 1/3 Jewel Lake, 5'0 ft., Contra Costa Co., Calif. About 1:14. No response from the F who has been feeding at GHT 4-5 most of the afternoon. 4:30 p.m. M is out of the cat-tails feeding along with 4 of the 5 yq; he is moving S, the F is moving N at H 7; M at F9 going towards her giving a "purr" or "kurk" note; she gave a "poozb", moved to the platform at G8.10 climbed on it and went into the squat asch. He came over, climbed onto the platform, mounted but didn't get balanced and either fell off or was dumped. At least they didn't copulate, she got off the platform without preening and started to (4:33) swim off. He chased her, giving her a "purr-kurk-kurk" note and trying to grab her head; she dived to get away. He stopped to feed and she preened when she surfaced, then moved to her usual post for feeding where she is at 4:38 p.m. 4:39 the F was on the platform preening but a moment before an immature was also seen. Now he has moved out to F8 to feed on pondweed. Univ. Calif. Campus, Alameda Co., Calif.
