SECOND LIST OF BIRDS OF THE BERKELEY CAMPUS 
39 
cavities have been destroyed in this manner, and the birds thereby deprived of 
their homes. Nesting dates are indicated by the finding of a brood of young in the 
nest, May 12, 1913, and five young still fed by their parents but flying about, 
May 29, 1913 (H. C. B.). 
Santa Cruz Chickadee. Penthestes rufescens barlowi. Casual fall visitant, 
or sporadic transient. One individual put in its appearance in the live-oaks 
around the Museum of Vertebrate Zoology during October, 1913, and was ob- 
served at different times by many interested people. It was first seen October 
4, but has not been reported since October 25. On the 21st it was watched from 
the northeast windows of the Museum building as it foraged in the oak foliage 
within a range of ten feet, thoroughly displaying the color-features which char- 
acterize the race barlozvi, to the satisfaction of all beholders (J. G., H. C. B., T. 
T. S., M. W. W., and others). 
This race of Chickadee belongs in the Santa Cruz faunal district, that is, the 
coastal area south from San Francisco into Monterey County. Judging from the 
climatic peculiarities of the immediate vicinity of Berkeley, it would appear con- 
sistent with our knowledge of geographical distribution to expect that, with the 
aging of our planted groves of conifers, chickadees will find conditions favorable 
to the establishment here of permanent colonies, as with the Olive-sided Fly- 
catcher and other boreal, and at the same time aboreal, species. 
Coast Bush-tit. Psaltriparus minimus minimus. Abundant resident of oak 
groves and chaparral, wherever these associations occur, all over the Campus. Ex- 
treme nesting dates : nev/ly completed nest, up Strawberry Creek canyon, Marcli 
2=5, 1911 (I- G.), and nest with young, near Center Street entrance, June 8, 1911 
(IT. C. B.). 
Intermediate Wren-tit. Chamaea fasciata fasciata. Abundant resident of 
the chaparral-clothed areas among the hills. Pairs or family parties occasionally 
rove down along the stream-courses clear across the Campus, rarely to city 
gardens. 
Western Golden-crowned Kinglet. Eegulus satrapa olivaceus. Fairly 
common mid-winter visitant, affecting oak-trees on the Campus proper, as well 
as up along the canyons. Dates of arrival: October 17, 1908 fj. G. ) ; October 
3, 1912, and October 10, 1913 (A. S. A.). Not reported later than January 20, 
1912 (J. G.). 
Western Ruby-crowned Kingi.ET. Eegulus calendula cineraceus. Abun- 
dant winter visitant to all sorts of arborescent vegetation, from chaparral and 
garden shrubbery to the oldest evergreen groves. Dates of first observation 
in the fall: October 2, 1904, October 10, 1906, and October 6, 1907 (A. S. A.) ; 
October 6, 1908, and October 10, 191 1 (J. G.) : October 3, 1912 (H. C. B.) ; Oc- 
tober 13, 1913 (A. S. A.). Latest spring record: April 13, 1912 (T. I. S.). 
Sitka Kinglet. Eegulus calendula grinnelli. Rare mid-winter visitant. 
Tanuary 23, 1911. a male of this subspecies foraged .some minutes througn the 
oak foliage within a few feet of the observers (FI. S. S. and J. G.), who were 
enabled to make a satisfactory comparison with the ordinary Ruby-crowns out- 
side the window — and with .skins inside! Other individuals have been identi- 
fied on the Campus as of this race, but not under such favorable circumstances. 
Western Gnatcatcher. Polioptila caerulea obscura. Observed only by 
Mrs. Amelia S. Allen, who has records of single individuals seen repeatedly in 
the chaparral above Mosswood Road. Actual dates of record are: October 
4 and 12, and December 28, 1912; September 23, 1913. Apparently to be clas.sed 
as a transient.
