129 CHESTNUT BACKED TITMOUSE
|Mr. NUTTALL'S notice respecting the present species is as
"The Chestnut-backed Titmouse is seen throughout the year in the forests of the Columbia, and as far south as Upper California, in all which tract it breeds, forming, as I have some reason to believe, a pendulous, or at least an exposed nest, like some of the European species. It is made of large quantities of hypna and lichens, and copiously and coarsely lined with deer's hair and large feathers, such as those of the Grouse and the Jay. They are commonly seen in small flocks of all ages in the autumn and winter, when they move about briskly, and emit a number of feeble querulous notes, after the manner of the Chickadee, or common species, Parus atricapillus, but seldom utter any thing like a song, though now and then, as they glean about, they utter a t'she, de, de, or t'dee, t'dee, dee, their more common querulous call, however, being like t'she, de, de, vait, t'she, de, de, vait, sometimes also a confused warbling chatter. The busy troop, accompanied often by the common species, the Regulus tricolor, and the small yellow-bellied Parus, are seen flitting through bushes and thickets, carefully gleaning insects and larvae for an instant, and are then off to some other place around, proceeding with restless activity to gratify the calls of hunger and the stimulus of caprice. Thus they are seen to rove along for miles together, until satisfied or fatigued, when they retire to rest in the recesses of the darkest forests, situations which they eventually choose for their temporary domicile, where in solitude and retirement they rear their young, and for the whole of the succeeding autumn and winter remain probably together in families. When the gun thins their ranks, it is surprising to see the courage, anxiety, and solicitude of these little creatures: they follow you with their wailing scold, and entreat for their companions in a manner that impresses you with a favourable idea of their social feelings and sympathy."
Mr. TOWNSEND says, that "the Chinook Indians call this species a kul. It inhabits the forests of the Columbia river, where it breeds and goes in flocks in the autumn, more or less gregarious through the season. The legs and feet are light blue."
