GULLION 1950 Fulica Americana 444 May 20 Palo Temescal, 420ft, Alameda Co., Calif.- it is 8:20 as they feed at G 23 and E♀ forages at N12. The W Territory apparently no longer exists. 8:25 as I feed the ♀ Mallard w/10 young. the SE♂ comes across, "swans" causing the ducks to move S, the ♀ Duck, hisses and gets her N wood back N. A pair of Mallards by the nest have the SE⬆ coughing. The SE♀ being unsuccessful with the hen attacks a Drake lurking in the willows, but he moves only a few feet before settling down again. 8:36 - SE♂ was right in by the nest, on the ramp, but no change occurred. 8:49 a. m. SE♀ attacked a ♂ Mallard at L 4, he didn't give in but strucke back at her, she churned and swarmed and then really assailed him, he flew a few feet and settled back down. Mallards thus for this year have shown no respect for the SE territory, and when attacked move only far enough to avoid the immediate contact. The Eots have not pressed any attacks, chasing or threatening for only a few feet, never- following up on initial onslaught. This condition may change as soon as they have young. I believe the SW pair now are pretty effectively keeping their area clear of Mallards at least. 8:57 - ♀ went directly to the nest from L6.) and as she approached the ♂ came off. The whole matter
