Fulica americana 354 Apr 28 Lake Tomsacal <20 ft. Alameda Co. Calif. - dived near the nest clump a couple of times and then passed S. At 4:29 a couple of "pubk's were heard from near P16 and at 4:30 the E ♀ is coming back towards its nest. 4:33, I stood up to put a shirt on, the E ♀ immediately got in an aggressive position just S of the nest. 4:35 he left the nest going R23. The ♀ sitting on the nest is facing N. 4:37, he is diving for and feeding on decomposing cat tail stalks. R23.17. He seems to have quite a taste for them. It seems to be the stems not the leaves that are eaten. 4:40, as ♀♂ Mallards fly around overhead, the ♂ at R23, // gives a couple of pubk's. At 4:44 p.m. the E ♀ went into the nest clump at the S, gave some low "pubk, pubk" notes, the ♀ responded by getting up and off the nest and the male crawling on. She went to R24, found a pair of Mallards there and routed them, chasing the hen first and then the drake. When the ♀ leaves the nest she goes away and stays away for long periods of time, but the ♂ seems to stay around close enough to be able to reach the nest quickly. At 4:59 p.m., a "prunk, plunk-plink" down S. that a subject is there ♀. 5:04 p.m. a bird (illegible) feeding at R17 under the willows, tipping for
