Aphelocoma californica californica (Vigors). California Jay. 
With the exception of the one case noted beyond, this species 
was seen only in the Upper Sonoran zone. California jays were 
numerous on the south side of the mountains in the serub oak 
belt up to the lower limit of the pines. It was also noted in the 
pinion belt on the north side of the mountains down to 5500 feet, 
below Cactus Flat, and up to 7500 feet on the north base of 
Sugarloaf. In the latter place August 19 to 23, 1905, they were 
feeding on service-berries in company with blue-fronted jays. 
They were seen in a tongue of Upper Sonoran on the south face 
of Sugarloaf, 6800 feet altitude, July 3, 1905. Late in the sum- 
mer these jays were noted outside of their usual range. Several 
were seen in the willow thickets at Bluff lake, 7500 feet, among 
the firs and pines, from August 29 to September 3. In July in 
the same locality none were seen. The inference is that these 
had wandered up and over temporarily from the serub oak belt 
on the south side of the ridge. 
Five specimens were taken. 
Corvus corax sinuatus (Wagler). American Raven. 
Several ravens were seen sitting around on dead trees near a 
slaughter pen at Coombs’s ranch just south of Bear lake, August 
28, 1905. They were not as wary as usual, and I suppose are 
usually let alone, along with the turkey vultures. Several were 
seen at different times flying over Bear lake, and one was seen at 
Knight’s ranch a mile or so south of Baldwin lake. 
Nucifraga columbiana (Wilson). Clarke Nutcracker. 
The Clarke nuteracker was met with chiefly from the fir belt 
(upper Transition) up to timber limit (through Boreal). It 
was particularly noticeable about San Gorgonio peak. Early in 
June young were full-grown, so that it must have been long past 
the breeding season. The plumage of the young is softer and 
their bills shorter, than with the adults. In two juvenal speci- 
mens out of eight taken the tips of the feathers on the breast are 
white, giving a spotted appearance. I do not find this previously 
noted in the case of our North American Nucifraga; but it has
