Hudsonian Chickadee
740. Penthestes hudsonicus. 5 inches.
Range.—Western half of British America. Habits the same as above.
Chestnut-Backed Chickadee
741. Penthestes rufescens. 5 inches.
Range.—Alaska to Oregon on the Pacific coast, and occasionally to central California. Habits the same as preceding.
California Chickadee
741a. Penthestes r. neglectus. 5 inches.
Range.—Middle section of California, near the coast (not illustrated).
Bush-Tit
743. Psaltriparus minimus. 4½ inches.
Range.—Pacific coast of California, Oregon and Washington. In habits all of these birds are similar to the Chickadees. They are full of life, and in searching for insects are as much at home when upside down on the outer end of a bunch of pine needles as are the Chickadees. For nest building they have no superiors, making long gourd-like structures of fibers, moss, and grass, woven closely together, lined with feathers and wool, suspended from twigs at a low elevation or woven into some thick brush; they have a small opening near the top for the doorway. They lay from four to nine pure white eggs (.54 ×.40).
