 Jan.,1914 SECOND LIST OF' BIRDS OF THE BERKELEY CAMPUS 31 some fence-post. Occurs in winter. around the Campus buildings, where, with some individuals, a regular roost has been chosen on some projecting cornice or on the tip of a flag-pole. BARN Owt.. Alu00 pratin0ola. Common r6sident. Many roost during the day around the buildings on the Campus, and after dark become much in evidence through their wierd vocal demonstrations. They forage far and wide over the city as well as among the hills, feeding exclusively on mice and gophers. A brood was reared on the roof of South Hall in the summer of 1913. CAt. IFORNA SCREECtt Owt.. 0tus asio bendfrei. Common resident. The mellow trill is often heard at night among the oaks of the lower Cainpus. On the afternoon of October 22, 19o8, a Screech Owl was located in a bay-tree near the Faculty Club, where it was being "mobbed" by a much agitated aggregation of Kinglets, Audubon Warblers and Titmice. In one instance a pair of these little owls found its way into the Harmon Gymnasium where its presence excited con- siderable comment. PAClFlC HORNED OWl.. Bubo virginianus pacificus. Common resident, The sonorous calls may be heard almost nightly along the east side of Berkeley, emanating from among the hills. Many feathers of Horned Owls are often to be seen along the barbed-wire fences over the hills, where the birds evidently go on the look-out for meadow-mice. A pair of Horned Owls has roosted from time to time for several years in eucalyptus or cypress trees on the northeast side of the Greek Theatre. The stomach of a bird shot in the Berkeley Hills contained two meadow-mice and 27 Jerusalem crickets (H. C. B.). BELTED KltqCFSER. Ceryle aleyon. On August 20, 1.9o8, one visited a goldfish pond at Mr. Warren Cheney's garden, 2241 College Avenue; no fish were actually taken out, but one was found dead the next day with a wound in its side (A. $. A.). WILLOW WOODPECKER. Dryobates pubescerts turati. Resident in very sinall numbers. .A pair has its regular forage-beat along the lower course of Straw- berry Creek, from above the College Avenue entrance to the Sather Gate. Live- oaks are worked upon principally. NUTTALL WOODPECKER. Dryobates nuttalli. On July 16, 193, one was close- ly observed by Dr. L. H. Miller and his summer--session class. It was working in the oaks in Strawberry Creek canyon just above Senior Women's Hall. SIERRA RED-BREASTED SAPSUCKER. Sphyrapicus varius daggetti. Irregular winter visitant in sinall numbers. Seen as early as September 3 o, 19o 4 (A. S. A.). A !ate spring date was March 18, 19It (T. I. S.). Most often detected in January and February. One bird worked daily one winter season in the oak at the northeast corner of the Museum building. The bark of tim upper branches of this oak is riddled with little holes, arranged in transverse circles. Some these series are evidently many years old. CALIFORNIA WOODPECKER. Melanerpes formicivorus bairdi. Ir'regxllarly resi- dent. Said to have been numerous many years ago Not seen of late years, til September 7, 1911 (T. I. S.), when a pair put in its appearance among the oaks of the lower Campus. Thenceforth observed in the vicinity at freqt:ent in- tervals until September 15, 1912 (A. S. A.), after which date none was seen. The presence on the Campus of as many as three pairs was accounted for at one time, March 19, 1912 (J. G.). LEWIS WOODPECKER. Asyndesmus lewisi. September r7, 911, at lO A. ., one was plainly' seen in north-to-south flight overhead about in line with Bacon Hall (H. S.S. and J. G.). Professor William E. Ritter has informed the writer that this woodpecker was formerly a not uncommon visitor to the Campus.
