GULLION 950 Fulica americana 277 Apr. 5 Univ. Calif. Campus, Alameda Co., Calif. - about the external environment. I have not seen [V]B[39] have any chance to settle on the nest. [V]B[39] cleans the pool out when [O]/E/ isn't in it [W]B just chased red-hill [X]R. P/O is carrying cat-tail leaves from the "nest" to the corner. [W]B slapping his foot on the pile of leaves. [B]r chases O/[B]r. [V]E[39] trying to settle on the nest was chased off by [V]E/. [W]B standing near the nest in an arch, punking in a low voice, and occasionally slapping his foot. [X]R swimming in the pool and vigorously feeding on numerous insects floating on the surface. Now all is quiet. 8:20 - this section started about 7:50 a.m. [O]/E/, [G]B[39], [W]B O/P all nesting in SE corner, joined [X]R, [B]r, [other X] in S center; the other one must be over in the SW corner. O/[B]r. In the pen P/LG is consistently pecking at [L]B as it gets the chance. O/[B]r was in the cat-tails rather than the SW corner. [O]/E/ sure has yellow legs, and [E]B[39] has yellow green legs. Whenever O starts sniping into the pen the birds outside immediately get aggressive and start chasing and making noises,
