Fulica americana .448- May 20 Lake Temeccal, 450 ft., Alameda Co., Calif. — to keep out of the way of SE birds enough to bring off a brood at K7, but I'll be surprised if they do. Note: — Bissell, in Zoo 145 class this morning said he had seen 2 parents and 3 young coots of on Jewell Lake on May 14 (Sunday). He said they were towards the SE end, that is in the marshes DE 10411. May 22— same locality — at 11:51 a.m. SE♀ is on nest J6.5. Egg D in nest J6.5 is the only one pipped, but all are satisfactorily warm. Sizes A 36.2 x 52.1 B 35.6 x 52.9 C 35.7 x 50.6 D 34.7 x 49.7—pipped E 36.1 x 52.1 F 35.4 x 52.0 G 34.8 x 53.7 H 34.9 x 50.5 I 34.2 x 50.9 J 33.5 x 51.8 —all in millimeters. As I waded out to the nest and both parents were displaying, M♂ at K9.1 cackled encouragement. The SE♀ was foremost in nest defense, as she usually is. Egg D is very recently pipped since none of the shell is gone, but it is broken into about 5 pieces. The cat-tails at [illegible] K7.16 and .L 7.21 have been badly broken down since May 20 a.m. I don't know whether or not that's going to affect M's nesting, since it leaves the nest very exposed from shore. Nest K7.17 seems somewhat enlarged so perhaps it is still building. M♂ seems to be tolerated by SE ♂
