30 THE CONDOR Vol. XVI Swallow, Yellow-throat, and Red-winged 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 her0dias hyper0nca. A rare transi- ent. One seen in flight high over the Campus at 8:30 ?x. ?w., April 5, I913 (H. C. B.). BLACK-CROWNED NIGHT HERON. Nycticorax nycticorax naevius. Occnrs as a transient only. The harsh "squawk" has been heard on several occasions at night during the month of September (J. G.). November 2, I9I 3, three were noted flying low over the hills in a fog (H. C. B.). KILLDEER. 0xyechus v0cfferus vociferus. Transient only. Heard in flight overhead in April and in August (J. G.). 'CALIFORNIA Q?JAIL. L0ph0rtyx californica Calff0raica. 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, I912, a bmod of nine young were hatched in a nest beneath one of the little red- wood trees at the back of the Museum building. This brood, with the two alert and constantly attendant parents, remained in the vicinity for five days, before moving up Strawberry Creek to wilder ground. On July IO, there was still the full quota of nine young, which indicates astonishing success in eluding the many prowling cats hy night and dogs by day. BAND-TAILED PIGEON. Columba fasciata fasciata. Sporadic winter visitant. On January 5, I913, 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 wiud (J. G. and H. W. G.). WESTERN i?[OURNING DOVE. Zenaidura macroura marginella. Casual transi- ent. On May II, I913, at I2 M., a solitary dove was seen flying swiftly north just over the tree-tops near Budd Hall (J. G.). TumrEY ULTUaE. Cathartes aura septentrionalis. 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, I912 (J. G.). SHAR?-SHINNED HAWK. Accipiter velox. Common winter visitant. Earliest fall records: September 3 o, I9IO, September 22, I912, and October I8, I9I 3 (J. G.). Seen on all parts of the Campus, and even among shade-trees along city streets. Coo?ER HAWK. Accipiter cooperi. Fairly common winter visitant. Ob- served only along the upper part of Strawberry Creek canyon. Early record: September 15, I912 (J. G.). WESTERN RED-TAILED HAWK. ltute0 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, I912, in the Berkeley Hills contained one meadow-mouse and two Jernsalem crickets (H. C. B.). This is the nsual big "chicken-hawk", though not fairly so called, in sight almost con- tinually, and circling' or poising against the wind above the ridges. AMERICAN SeAlmOW HAWK. ?ale0 sparverius sparverius. Fairly common resident. Often seen about the hilltops, hovering against the wind, or perched on
