THIi CONDOR 
155 
generous sprinkling of Lower .Sonoran birds is found, including Zamelodia mcla)w- 
cephala, Doidroica wsHva and Pipilo inaculatus iJicgalo}iyx, while many birds of the 
Canadian zone extend down as low as 3,700 feet and are found breeding abun- 
dantly. Sphyrapicus ruber, Dryobates viUosus hvloscopus and Cyanocitta stellcri fro)i- 
talis may be considered typical of Transition, while the more typical forest trees 
of this belt are the yellow pine { Piuiis pouderosa), sugar pine (Pi)ius lambertiana'), 
incense cedar {Liboccdriis decurreus) and Douglas spruce ( Pscudofsuga utucrouaia). 
ON THE SUMMIT OF PYRAMID PEAK. 
The Canadian zone along the route may be included in the region lying be- 
tween 5,000 feet altitude and the summit with its average elevation of 7,500 feet, 
irrespective of its numerous peaks. Here we find Sphyrapiciis ikyroidcus, Dcndra- 
gapHS obsciu'us fuligiinrsus and Cocco/Praustes vcspcrPnus montanus, and such trees 
as the lodgepole pine [Piuus iiui)'rya)Hi), red fir (Abies magnifiea), silver pine 
(Pinus uwnticold) and ( JiDiiperus oceideufalis). The Hudsonian zone proper 
is encountered from about 8,000 feet upward on the slopes of the higher peaks, typi- 
cal birds being AP/cifraga cohnubiana , Zonotriebia leucophrys, Spinus pinus and Reg- 
uius calendula. This region is characterized by its hemlock forests. The Alpine 
zone on Pyramid and other peaks is a narrow belt above timber-line and the only 
bird observed was Leucosticte lephrocotis. 
RKChiXT WORK IN THK RliGION. 
This brief survey is intended to cover only comparatively recent work in the 
region under consideration. Mr. \\\ W. Price made his first investigations in the 
summer of 1893 and has since devoted three months of each year to the explor- 
ation of the country contiguous to the stage road. His twenty-seven month’s ex- 
perience has made him familiar wdth even the more remote portions of the region, 
so that the addition of his notes to the present list insures its rea.sonable complete- 
ness. 
During the summer of 1896 Messrs. Wilfred H. CXsgood and R. H. Beck made an 
extended collecting trip from Placerville to Tallac and several particularly inter- 
esting sets of eggs (including the type .se of Dendroica occidentalis and Cocco-
