TITMICE AND BUSH-TITS: Family Par idae [435] 



ing one egg on Canyon Mountain on June 8, 1876 (Bendire 1877). Miller's 

 (1904) records from Wheeler County in 1899 doubtless belong here. 

 Jewett's (19090) specimens from Baker County and Gabrielson's (192^) 

 birds from Wallowa County are also of this race. This and the next race 

 are the present names of the subspecies of the familiar Mountain Chick- 

 adee. 



Short-tailed Chickadee: 



Penthestes gambeli abbreviates Grinnell 



DESCRIPTION. Similar to Grinnell's Chickadee but with slight differences in color 

 shading and with a relatively shorter tail. Si%e: Length 5-6, wing 1.70, tail i.zy. 

 Nest and eggs: Similar to those of Grinnell's Chickadee. 



DISTRIBUTION. General: Cascades and southern range of Oregon, northwestern 

 Nevada, northern and eastern California south to Mount Whitney. In Oregon: Per- 

 manent resident of Cascades, Siskiyous, and ranges of Klamath and Lake Counties 

 east to and including Hart Mountain in east-central Lake County. Has strayed to 

 Portland and Netarts in winter. 



THE SHORT-TAILED CHICKADEE is the breeding form in the Cascades, the 

 Siskiyous, and the isolated ranges from west of Bend east and southward 

 to and including Hart Mountain in eastern Lake County. Six October 

 specimens in our collection from the head of Marks Creek, Little Summit 

 Prairie, seem to be closer to this form than to Grinnell's Chickadee. Birds 

 from Redmond, Pine Mountain east of Bend, Silver Lake, Lakeview, and 

 Hart Mountain record about the eastern limit of the range, and similarly 

 a summer skin from Bolan Mountain, Josephine County, in Jewett's 

 collection, marks its western limit so far as known at present. 



Jewett (i9O9d) recorded a winter straggler "along the Columbia," 

 December 10, 1908, and Walker (192.6) published a record of a specimen 

 taken at Netarts, December 17, 192.4, which are the only two records 

 west of the Cascades north of the Siskiyous. Baird (Baird, Cassin, and 

 Lawrence 1858) recorded a specimen of Mountain Chickadee taken by 

 Suckley at Fort Dalles in February 1855, but in Cooper's report (Cooper 

 and Suckley 1860) Dr. Suckley said: "I obtained one of these birds at 

 Fort Dalles, in February 1854. It must be very rare in that vicinity, as 

 I never succeeded in getting another." Norris (1890) reported eggs taken 

 at Fort Klamath, June 8, 1890, and both Mearns (1879) an d Merrill (1888) 

 found this chickadee abundant at the same spot. Since this time it has 

 been listed by numerous observers and writers. 



Aside from the Norris record, we have only the following nesting data: 

 Three nests were located by Jewett, June 14, 192.3, southeast of Lapine 

 on the Deschutes National Forest. The first contained eight small young 

 just out of the eggs; the second, six eggs advanced in incubation; and the 

 third, seven eggs one broken, three addled, and three in an advanced 

 stage of incubation. Two of these nests were built in lodgepole pine
