Eullion 1949 Fulica Americana -6- Apr 9 Lake Jewell, Tilden Park, Contra Costa, Calif. This bird left the area, crossing the lake to position (3) where she nervously fed. About that time the large bird came out "crunking". He remained on the scene - and steadily crunked as I searched. When I found the nest he came to within about two feet of me - vigorously protesting - the female? meanwhile remaining silent across the lake - Eggs in the nest - several coat, three or four quite warm (from sun?) - about 3 feet of water under nest - composed of dried cat-tails - with only a couple of green cat-tails in the vicinity - nest quite well concealed by upright dense masses of dried cat-tails. The male quieted down a few minutes after I left the vicinity of the nest. - about 2:15 p.m. one bird was loud calling "kra-kow"; "kra-kow" along the E side of the lake - near position (4). A moment later - to a smaller bird was moving by the boat towards the island - was met at the SE corner of the island by a larger bird, who tried to mount her twice but without success - he? flew a couple of times and she moved back past the boat - he followed her as far as the boat, stopping to rest and preen on the outer side of the boat - a drake mallard was resting on the misthos gunwale - until a couple of birds came along to scare him away.
