others seen among the cottonwoods surrounding the springs, and 
among the tree yuceas of the surrounding desert. 
Dryobates nuttalli (Gambel). Nuttall Woodpecker. 
In June and July of each year, Nuttall woodpeckers were 
quite common on the upper Santa Ana in the vicinity of Seven 
Oaks (5000 feet). They were evidently breeding there among 
the alders and cottonwoods. After the youhg were full grown 
individuals wandered up along the Santa Ana as far as the south 
fork and even Fish creek, where examples were seen and taken, 
August 2 to 4, 1906. This species was encountered in only one 
other portion of the mountains, on the desert slope at Cactus Flat 
(6000 feet), where a pair were seen August 17, 1905. These were 
in golden oaks, a limited tract of which oceur in a ravine on the 
northeast side of the range. This record station is of interest as 
being so near the range of D. scalaris bairdi. 
Four specimens of the Nuttall woodpecker were obtained. 
Xenopicus albolarvatus gravirostris (Grinnell). 
Southern White-headed Woodpecker. 
White-headed woodpeckers were unexpectedly searce in the 
San Bernardino mountains. In no place were they as numerous 
as I have found them elsewhere in the mountains of Southern 
California. They were seen only in the Transition zone, none 
being observed above the fir belt, and but very few down into 
pure yellow pine tracts. In the vicinity of Fish ereek, 6500 feet, 
a few pairs were breeding in June. On July 5, 1905, I found a 
nesting hole seven feet up in a dead pine stub, which contained 
four half-fledged young. We did not see the species anywhere 
higher than about 8000 feet, except on the south slope of Sugar- 
loaf, where on July 11, 1906, one was seen among the silver firs 
at about 9000 feet altitude. About Bluff lake they were more 
common than anywhere else, and a few were seen on the northern 
slopes of Sugarloaf at about 8000 feet, in August. Youne and 
adults taken before the fall moult set in were in some eases fear- 
fully smeared with pitch ventrally. <A full-grown juvenal, taken 
at Bluff lake, July 25, 1905, is a freak in that it has a patch of 
white feathers in the normally black belly region. Their food
