Banks 1956 Sayornis nigricans 28 April, 1956, Hopland Exp. Sta., Mendocino Co., Calif. Nest of mud with some grass on building side under overhang roof, about 2 inches below roof. Nest O-shaped, about 4 inches in diameter. 4 eggs, white with a few speckles of black scattered over them. Another nest in similar location and of similar construction on old barn near H.Q. contained young. U.C. Campus, Berkeley, Alameda Co., Calif. 3 Nov. A bird was seen on the N. side of LSB, outside MVZ, near the ledge and word "Anatomy". (One seen less about 1 P.M. one day a couple weeks ago). This one was heard, then seen catching insects from this ledge. It next flew to a horse chestnut tree near the corner of MV2. Here it replaced a Hyloiclla ustulata, and may actually have chased it. The thrush also was "fly-catching". The phoebe remained in area for at least half an hour. (See Hyloichla ustulata, sp. act.) It remained a very short time in the tree, about 10 ft. off ground, then returned to the ledge and the top of a poplar tree by steps. Later: 1:10 P.M. Phoebe still here, near back of horse chestnut, moving toward NW corner MV2. It is chipping constantly, a loud, single note, down- slurred a little, with an upward jerk of the tail accompanying each note. Observed in same area again at 3:05 and 3:45 P.M.
