industriously running a line of bark-pits around the branch of 
an alder, when a California woodpecker, which we will presume 
had been watching operations from his perch on a tall dead pine 
across the ravine, flew down and drove off the sapsucker; the for- 
mer then went the rounds of the borings himself, ‘‘dipping”’ 
from each! © . 
Colaptes cafer collaris (Vigors). Red-shafted Flicker. 
Flickers were found in the region but sparingly, as compared 
with their usual abundance in other parts of the country. At 
8500 feet elevation on the upper South Fork of the Santa Ana, 
a nest was found 78 feet up in a dead yellow pine. The bird 
visited it regularly, giving three notes each time to announce his 
coming, sounding like ‘‘claip;’’ then he inserted his head into 
the hole and ‘‘pumped”’ three times, evidently delivering a con- 
signment of ants. Oceasional flickers were noted throughout the 
black oak belt from Fish Creek to Foresee creek. One was seen 
at Dry lake, 9000 feet, June 22, 1905. Flickers were noted 
around Bluff lake, a few around Bear lake and several on the 
north side of Sugarloaf. A specimen which was taken at a 
spring at Cactus Flat, August 17, 1905, smelt very pungently 
of a kind of strong-smelling ant, usually altogether passed over 
by birds. 
Phalaenoptilus nuttalli californicus Ridgway. Dusky Poor-will. 
Poor-wills were heard along the road, 4500 feet altitude, below 
Clark’s ranch on the evening of June 12, 1905. Later in the 
month others were heard in the vicinity of our camp at Fish 
creek, 6500 feet, where a tongue of pifons extend along the 
south-facing canon-side. They were not seen again until we 
reached Doble, August 5 to 6, where they proved common, and 
two specimens were secured. On the evening of August 22 we 
secured a pair at the edge of the sage flat at the north base of 
Sugarloaf at 7500 feet altitude. The specimens taken are all in 
juvenal plumage. One of these, taken August 22, shows many 
feathers of the full adult plumage in the throat and breast. The 
juvenal plumage is characterized by having the throat patch buff 
and the back conspicuously mixed with cinnamon-rufus.
