ROCKY MOUNTAIN CREEPER.

726b. Certhia familiaris montana. 5½ inches.

Range.—From Alaska, in the Rocky Mountains, to southern California and Mexico, breeding throughout its range. A quiet, small, brown colored bird of the deep woods, where its lisping note may be heard, if the air is very quiet, and one is looking for bird life. When found, it will generally be climbing up the trunk of some tall tree, searching the crevices of the bark for the small insect life on which it feeds; when near the top, a downward flight to the base of another tree. Always flying down, and climbing up. Their nest is placed in the loose bark, and is made of fiber, moss and grass. They lay from four to seven white eggs, spotted with chestnut (.58 × .48).
