llion 49 Fulica americana -32- May 28 Jewel Lake, Wilder Park, Contra Costa Co. Calif. paired display. The south male started to move off only to be closely pursued by both of the north birds. I missed a moment, and in that time apparently the north ♀ turned off moving W to the cat-tails and the south male turned on the north male, chasing him over the water for about thirty feet. They settled down in paired display again, each threatening the other and the ♀ came in to rejoin her male. At that moment one of the young of the S brood came into the area, giving a "inquent" note. This young was promptly attacked by the north ♀. All lived as she came upon it, and at the same instant the S ♀ came spluttering to her youngs aid. The N ♀ dived at the onslaught of the S ♀ and escaped under water. All four birds then went into paired display, the two ♂♂ and the two♀♀ each opposing their like number. For a moment the 2 ♂♂ sat back on their tails to look at each other with their feet, but this was short lived. To this the octup broke up, with each bird moving off in typical separation behavior, except that they didn't seem to be diving. During this time the broods seemed to be scattered all over the lots.
