Eastern California Occurrences of the Golden-crowned Sparrow.—That Zonotrichia 
coronata is a common migrant along the eastern Sierras, is indicated by the following‘ 
personally taken notes. The locality is 6700 feet altitude and just east of Sierra City, 
Sierra County. October 5, 1911, one immature‘taken and two more seen; October 6, 
half a dozen seen, two of which were adults; thereafter increasingly common until Oc- 
tober 18 when they out-numbered Zonotrichia 1. gambeli about two to one; thereafter 
decreasing in numbers till November 8, when one was taken. At this last date there 
was two feet of snow at this altitude, and open ground under heavy brush must have 
been difficult to find. In 1916 an adult female was taken September 23. ‘Little time 
was available for collecting that year so that the single entry does not necessarily 
indicate any scarcity of birds. In the D. R. Dickey collection is an immature bird taken 
by L. M. Huey at Potholes, Imperial County, April 18, 1916. This is a short distance 
up the river from Yuma and is therefore practically on the Arizona line——A. J. VAN 
RossemM, Los Angeles, California, March 25, 1921. 
Sparrow Hawk Captures Swallow.—On April 26, 1921, at Stanford University, 
California, the following observation was made on a Sparrow Hawk (Falco sparverius). 
A number of Cliff Swallows (Petrochelidon lunifrons) were building, or repairing, their 
mud nests on the north side of the museum just under the eves. The hawk was about 
one hundred yards away on the top of a young redwood tree. While we watched him 
he sailed gently down to one of the swallow’s nests, passing over a group of about 
fifteen people, supported himself with one foot, hanging nearly upside down in the mean- 
time, inserted the other foot into the nest, and extracted its owner. The captured bird 
was an adult Cliff Swallow. The nest was not very deep, and the opening was large. 
‘The swallow was building up the broken opening when attacked.—PauL Bonnot, Stan- 
ford University, California, April 28, 1921. 
Bubo virginianus occidentalis in California~—The Museum cf Vertebrate Zoology 
has recently received as a gift from Mr. Carl S. Mueller, of Marysville, California, his 
collection of bird skins, a large proportion of them being specimens collected by himself in 
various parts of California. Included in this collection are two horned owls of particular 
interest as representative of Bubo virginianus occidentalis Stone, a subspecies not be- 
fore recorded from California. These two birds, male and female, were taken at Shum- 
way,. Lassen County, on September 18, 1916. 
Compared with specimens of Bubo virginianus pacificus, from the region to the 
westward, they are paler, more grayish in general coloration, and with much less ad- 
mixture of reddish. They are also somewhat larger than the mode of pacificus. Com- 
pared with breeding examples of B. v. pallescens from the lower Colorado River and 
southeastern Arizona, these specimens of occidentalis are darker colored, they have 
rather heavily marked tibiae as compared with the frequently immaculate legs of pal- 
lescens, and they are of larger size. 
Presumably occidentalis is the form of horned owl that breeds in the Modoc re- 
gion of California, though breeding birds are lacking as yet to prove this. There are 
two young horned owls in the Museum collection from that part of the state which had 
been catalogued as pacificus but which are doubtless of the subspecies occidentalis. One 
was taken at the head of Pine Creek in the Warner Mountains, the other at the Scott 
Ranch, ten miles north of Alturas.—H. S. Swartn, Museum of Vertebrate Zoology, Berie- 
ley, California, May 138, 1921. 
Calliope Hummingbird at the Flower Show.—Spring comes rather late in the 
Yosemite Valley; however, Calliope Hummingbirds arrived April 6, this year. For the 
first few weeks they spent their time on the north side of the valley among the early 
blooming manzanitas, and no birds were seen south of the river until May 14. On this 
date a female Calliope discovered the Flower Show in the Village. 
This flower show is maintained at the Rangers’ Headquarters, and though flowers 
may be scarce, there is always a fine floral display here. The Calliope was quick to 
recognize the value of the floral display, and from the day of her discovery she was a 
constant attendant. The “hummer” appeared not the least disturbed by the crowds of
