It is perhaps the most abundant bird in Southern Illinois, where it is resident, being excessively numerous in winter, and in that season often a positive nuisance from their impertinent vehement scolding as they appear to follow the hunter in troops through the woods. In winter it is a constant inhabitant of the door-yards and shrubbery, particularly fruit-trees in the towns, where it is associated with the Carolina Chickadee (_Parus carolinensis_) and other winter birds, but exceeding them all in familiarity and boldness. (Ridgway.) Mr. Nuttall, who never met with this bird north of Pennsylvania, found it very common in the winter and spring in the Southern States, where it displayed all the habits and uttered the usual notes of the family. In the dreariest solitudes of the Southern States these birds were his constant and amusing companions. Their sprightly movements and their varied musical talents made it even more peculiarly interesting at a time when all the other tenants of the forest were silent. The notes of this bird, which, when expressed by this writer on paper, seem only quaint and eccentric articulations, were characterized by him as lively, cheering, and varied, delivered with a delicacy, energy, pathos, and variety of expression to which it was far beyond the power of description to do justice. These notes, at times, even partook of the high-echoing and clear tones of the Oriole. The usual song of this Titmouse is presented by Mr. Nuttall by the following characteristics: “_Whip-tom-killy-killy-dāy-dāy-dā-it-tshica-dēē-dee_,” varied with “_Kāī-tee-did-did-did_,” etc., etc. Later in the season, under the milder influences of spring, these Titmice pursued the insects from branch to branch, calling restlessly and with loud and echoing voices, _peto-peto-peto_, with frequent quaint variations too numerous to be repeated. Their song even consisted of successions of playful, pathetic, or querulous calls, never exhibiting any trills after the manner of the Warblers, yet the compass and tones of their voice, their capricious variety, and their general effect are described as quite as pleasing as the more exquisite notes of our summer songsters. When wounded this Titmouse resists with great spirit any attempt to take him alive, but soon becomes tame and familiar in confinement, subsisting on seeds, broken nuts, etc. Impatient of restraint, it incessantly attempts to work its way out of its cage. The general habits of these birds correspond closely with those of the large family to which they belong. They move usually in small flocks of from five to ten through the branches of trees and bushes in quest of insects, examine the cracks and crevices of the bark, hang on the under side of small branches, move sideways around the trunks of trees, probe the openings in acorns, pine-cones, nuts, etc., for its food, and retain apparently the family group until the spring, when they separate into pairs.
