Fulica americana May 22 Jewel Lake, 510 ft., Contra Costa Co., Calif.- The nest at M 25. 19 is sinking, has about 1/2 inch to go to be completely under the water. Probably in another week or so it will have settled completely. 2:15 still no coots. After looping clear around the W side of the lake, finding a ? Mallard nest with 4 warm eggs (marked) at 16. 22 (the hen was sneaking off when I was examining the nest) I finally saw 1 adult w/3 young swimming along the edge of the cat-tails from 6/0 to 1/17 where they disappeared. One young seemed to be pretty light on the breast, couldn't see too well but it may be getting the white breast. May 23 Lake Tomesca, 420 ft., Alameda Co., Calif.- At arrival at 5:25 p.m. No birds or nest J6. 5, the ♀ was feeding at J7 on the edge of the willows, seemed nervous and came over towards me when I appeared. As I approached the nest, the SE ♀ came out to meet me. Found the eggs all warm and D pretty well piped. Nest I 6.1 is very evidently in use as a brood nest. Some coarser material has been added toit and it is wet and much used. The carcass of a young is at the base of the ramp. It is dalmosty completely disintegrate, all the down gone and smoothly a mass of jelly. Both SW parents in the cat- tails
