THE CONDOR 
Vol. XVI 
Swallow, Yellow-throat, and Red-wdiiged Blackbird, will doubtless be added in 
course of time, at least as transients. Intensive observation from season to sea- 
son for a series of years may be expected largely to augment the list, judging 
from experience under similar circumstances eisewhere. This very element of in- 
completeness and expectancy serves as a continual incentive to those interested in 
bird study to be always alert for the detection of strangers as well as for addi- 
tional facts concerning well-known species. 
California Great Blue Heron. Ardea herodias hyperonca. A rare transi- 
ent. One seen in flight high over the Campus at 8:30 a. m., April 5, 1913 (H. 
C. B.). 
Black-crowned Night Heron. Nycticorax nycticorax naevius. Occurs as 
a transient only. The harsh “squawk” has been heard on several occasions at 
night during the month of September (J. G.). November 2, 1913, three were 
noted flying low over the hills in a fog (H. C. B.). 
KilldeEr. Oxyechus vociferus vociferus. Transient only. Heard in flight 
overhead in April and in August (J. G.). 
California Quail. Lophortyx californica californica. Common resident. 
While showing marked preference for tracts of chaparral among the hills, coveys 
and, occasionally in spring, pairs rove down over the lower Campus. On July 6, 
1912, a brood of nine young w^ere hatched in a nest beneath one of th.e little red- 
w'ood trees at the back of the Museum building. This brood, vrith the two alert 
and constantly attendant parents, remained in the vicinity for live days, before 
moving up vStrawberry Creek to wilder ground. On July 10, there was still the 
full quota of nine young, which indicates astonishing success in eluding the many 
prowling cats by night and dogs by day. 
Band-tailed Pigeon. Cohmiba fasciata fasciata. Sporadic winter visitant. 
On January 5, 1913, at ii a. m., a flock of eight was observed as it slowly skirt- 
ed the hillside below the Big C, flying against a strong north wind (J. G. and 
H. W. G.). 
Western Mourning Dove. Zeiiaidura macrotira marginella. Casual transi- 
ent. On May ii, 1913, at 12 m., a solitary dove was seen flying swiftly north 
just over the tree-tops near Budd Hall (J. G.). 
Turkey Vulture. Cathartes aura septentrioiialis. Summer visitant. Not 
infrequently seen in June and July in flight above the hills. 
Marsh Hawk. Circus hudsonius. Casual winter visitant. One seen harry- 
ing over the hillside near the Big C, September 15, 1912 (J. G.). 
Sharp-shinned Hawk. Accipiter velox. Common winter visitant. Earliest 
fall records: September 30, 1910, September 22, 1912, and October 18, 1913 
(J. G.). Seen on all parts of the Campus, and even among shade-trees along city 
streets. 
Cooper Hawk. Accipiter cooperi. Fairly common winter visitant. Ob- 
served only along the upper part of Strawberry Creek canyon. Early record: 
September 15, 1912 (J. G.). 
Western Red-tailed Hawk. Buteo borealis calurus. Common resident. 
Occurs all through the hills, where it feeds on the abundant meadow-mice. The 
stomach of a Red-tailed Hawk taken December 28, 1912, in the Berkeley Hills 
contained one meadow-mouse and two Jerusalem crickets (H. C. B.). This i^ 
the usual big “chicken-hawk”, though not fairly so called, in sight almost con- 
tinually, and circling or poising against the wind above the ridges. 
AiMERiCAN Sparrow Hawk. Falco sparverius sparverius. Fairly common 
resident. Often seen about the hilltops, hovering against the wind, or perched on
