Fulica americana -16- Apr 29 Jewel Lake, Tilden Park, Contra Costa Co., Calif. - also at a critical moment gave a low growling guttural 'rrrrr' sounding more like a growling dog. Apparently the larger bird was investigating the nest, for after I left he came 'pubk' ing across the lake, sticking close to the cat-tails along the dam. He got about as far as L 28 before he turned around and returned to the nest area. 1:15 p.m. At about 1:20 p.m. the male was with a young at N 26.16. Some billling was seen, then a moment later he started out into the open water leaving the young behind. I got out of the car just in time to see him join the female who was bringing all five young across the lake. They headed four into the cat-tails at L 22.24, and [illegible] the female went back out it's bringing a laggard at about the same place. Again the male was seen 'billling' at least one and maybe more of the young. Six of the seven out of the nest are still alive, and maybe the two in the nest will make it also. Nest C12, 13 warm at 6:10 p.m., bird about two feet away in cat-tails churning and giving the 'pubk' note occasionally. While pulling [illegible] some cat-tails out I disrupted the nest considerably, hope not fatally. Nest O 26.6 contains one viable egg, still being brooded, the young I helped hatch was nowhere to be seen, I hope is okay. The whole family apparently was in the area. Egg 1, the last still only about 3 pipped.
