W. GULLION 1950 Fulica Americana 421 May 15 Lake Tonescal, 420 ft, Alameda Co., Calif. Grown willow leaves since last visted. At this moment (5:48 pm) W/B + 2 UNM are feeding at N 12 not molested by an E bird at B 22. While he was at P 15 they started moving out to avoid his charge. 5:54 p.m. as I moved North along the road, the E & Splattered from N 12 to P 15 and from P 18 to P 21 to keep alreast me. When I arrived The E & came off nest B 22 - I could see at least 3 yrg on the nest. May 16 same locality - at 3:45 p.m. SE ? at L 2 - SE @ on nest J 6.5. About 4 p.m. one of the Sw yrg caught & clipped P 1. Egg #7 still pipped, but neither #8 or 10 are. Still no sign of #9. Both parents close by defending, but not on the nest. Nest at X 7.17 still being worked on, Structure at +17.25 pretty well worn down but still in use. Nest I 6.1, being on a group of slanting dead cat-tail stems, has not settled as if builds up, hence has grown to quite a structure. It is lined with pieces of short-cat leaves, perhaps being converted to a broad nest already. The nest at J 6.5, despite the vast amount of material piled on it has constant settled with the result that it is not a great deal larger than it has been for some time.
