Geococcyx californianus (II, 472). Has been found in El Paso County, Colorado, by Mr. Aiken.
Picus gairdneri (II, 512). Four eggs of this Woodpecker were taken by Mr. William A. Cooper near Santa Cruz, Cal., from a hole in a tree, one side of which was much decayed. Four is said to be the usual number of their eggs, although five were found in one instance. The eggs resemble those of P. pubescens, and measure .75 of an inch in length by .57 in breadth.
Sphyropicus varius (II, 539). Collected in El Paso County, Colorado, by Mr. Aiken.
Centurus uropygialis (II, 558). Captain Bendire found this Woodpecker the most common of the family in the vicinity of Tucson, Arizona, where it was resident throughout the year. Like nearly all of its kindred, it is an exceedingly noisy bird. It appears to be a resident species throughout the year in all the southern portions of the Territory. Its favorite localities for nesting appear to be in the gigantic trunks of the large Cereus giganteus, which plants are called by the natives Suwarrows. These are easily excavated, and form a remarkably safe place in which to rear their young ones, on account of the many thorns with which these cacti are protected. Their eggs are usually four in number, but sometimes are only two, and resemble those of all the other kinds of Woodpeckers in their color and in their rounded oval shape. They average .98 of an inch in length and .76 in breadth. Usually two, and occasionally even three, broods are raised in a season.
Strix pratincola (III, 13). Dr. Cooper informs us that, though most of these Owls are resident in California south of latitude 35°, there is a migration southward in fall from the north. Great numbers of them appeared near San Buenaventura about October 20, 1872, for a few days, and most of them went still farther southward. They return north about the first of April. On the 12th of April he found a nest built four feet up in a pepper-tree (Schinus molle), forming part of a hedge, composed of coarse sticks, straws, and dry horse-dung inside, shallow but strongly built, and containing two eggs.
