SECOND LIST OF BIRDS OF THE BERKELEY CAMPUS 
3,1 
branch over the path between the women’s tennis courts and the ilearst Gym- 
nasium. ’ 
Western Flycatcher. Empidonax difRcilis difRcilis. Common summer 
visitant. Arrivals have been noted as follows: March 28, 1906 (A. S. A.); 
March 21, 1911, and March 28, 1912 ( J. G.) ; April 1, 1913 (T. T. S.). Last for 
the season: September 24, 1908, and September 15, 1912 (J. G.). Nests are lo- 
cated along- shaded ravines and in the eucalyptus groves. In one case a brood 
was reared in a nest ensconced in a niche 18 feet above the ground in the side of 
an oak trunk near the Faculty Club. In another instance, the nest was built in a 
fern basket on a porch at 2243 College Avenue. This site was but hve feet from 
a frecjuently used door, and it was only two feet from the porch-light v'hich shone 
into the nest on frecjuent occasions in the evening without appearing to disturb 
the birds. On May 17 (1908) this nest held four eggs, and two young were 
successfully reared. In 1909, the same site was chosen, but the nest was subse- 
quently deserted (A. S. A.). 
Calieornia Horned Lark. Otocoris alpestris actia. A resident species in 
parts of the San Francisco Bay region, but detected on the Campus only once: a 
small company seen on the hillside near the Big C, April 3, 1912 ( T. 1 . S.). 
Coast Jay. Cyanocitta stelleri carbonacea. Fairly common resident. Ordi- 
narily restricted closely to the dense growths of bay, live-oak and madroha, up 
Strawberry and Woolsey canyons, and to the thick grove of planted evergreens 
around the Greek Theatre. In cloudy or foggy weather the birds rove down over 
the lower Campus, occasionally even to the Center Street entrance. This is 
typically a bird of the thick woods in the humid coast belt of California. Around 
Berkeley, which is somewhat outside of its metropolis, its choice of local environ- 
ment emphasizes these predilections. 
C.VLiFORNiA Jay. Aphelocoma californica calif omica. Abundant resident. A 
familiar and noisy forager all over the Campus. During the foot-ball season, the 
jays visit the bleachers regularly for scattered popcorn and peanuts. Acorns in 
their season constitute a preferred food-source, and many of these are buried by 
the jays, presumably for future use. Nests are constructed in oak-trees, some- 
times on the busiest parts of the Campus. One occupied nest observed Marcli 
25, 191T, was placed 25 feet above the ground in a centrally-situated foliage- 
mass directly over the sidewalk across the road south of the old Chemistry build- 
ing. 
Pin YON Jay. Cyanocephalus cyanocephaliis. Rare transient. On October 
5, 1911, at 2 i>. M., a flock of fully 75 was watched flying south over the Campus. 
The chorus of characteristic calls first attracted attention ; and this, together with 
the mode of flight and silhouette, rendered recognition perfectly satisfactorv ( LI. 
S. S. and J. G.). 
Western Meadowlark. Sturnella neglecta. Abundant resident on the 
grassy hill-tops. Also at times visits vacant lots in the city. Before close settle- 
ment of the lowlands, it abounded as a regular inhabitant throughout our region. 
Bullock Oriole. Icterus bullocki. Summer visitant in very small numbers. 
Dates of first seen: March 31, iqoq, April 6, 1911, April 13, 1912, and April 10, 
1913 (A. S. A.). A pair had a nest in 1908 in a eucalyptus tree near the Zeta 
Psi fraternity house on College Avenue (A. S. A.). A full-grown juvenal was 
seen near the Faculty Club, July 3, 1913 (H. C. B. ). 
Brewer Bi.ackbird. Eupbagus cyanocephalus. Common resident on the 
lower part of the Campus. A colony nests each year in the big pines near the
