Fulica americana 284 Apr 8 Lake Temescal, 420 ft., Alameda Co., Calif. - of my approach, then she stopped. Just now the E ♂ chased a ♀ Mallard out from P16 and gave him a good flogging. So interspecific strife is starting. The Mallard turned right back into the area he was just chased from, and the ♂ did not attack a second time. Finally saw 0 out feeding at J3 - he ran for the cat-tails when he saw me. The ♀ stayed on the nest when I returned to replace the weighed eggs at J6.5 until I started to reach in, then she jumped off, churned, growled, and moved to the open water where she was immediately joined by her mate. After about a minute her mate left, leaving her to defend alone. Remarked all eight eggs. This nest is much built up from its earlier condition with a very deep cup. The nest at J6.7 is in good shape too. The SW pair has a plat- form underway at H7.25, in a trail I made previously looking for a nest. Nest J6.5 was disturbed about 2:50 p.m. Finally at 3 p.m. she started onto the nest, climbing up the ramp, preening, adjusting cat-tails, in all taking about 1½ minutes before settling on the nest. After she was on the nest she gave a couple of low "punks"
