My friend THOMAS M’CULLOCH, Esq. of Pictou, in Nova Scotia, has favoured me with the following interesting remarks having reference to this species. “Sometimes I have been inclined to think, that the sight of this bird is comparatively imperfect, and that it is chiefly indebted to some of the other senses for its success in obtaining subsistence. This idea may not be correct, but it seems to derive some support from the little incident which I am about to mention. While standing at the edge of a patch of newly-felled wood, over which the fire had recently passed, and left every thing black in its course, I observed a small flock of these birds coming from the opposite side of the clearing. Being dressed in black and aware of their familiarity, I stood perfectly motionless, for the purpose of ascertaining how near they would approach. Stealing from branch to branch, and peering for food among the crevices of the prostrate trunks, as they passed along, onward they came until the foremost settled upon a small twig a few feet from the spot upon which I stood. After looking about for a short time it flew and alighted just below the lock of a double-barrelled gun which I held in a slanting direction below my arm. Being unable however to obtain a hold, it slided down to the middle of the piece, and then flew away, jerking its tail, and apparently quite unconscious of having been so near the deadly weapon. In this country these birds seem to be influenced by a modification of that feeling by which so many others are induced to congregate at the close of autumn and seek a more congenial clime. At that period they collect in large flocks and exhibit all the hurry and bustle of travellers, who are bent upon a distant journey. If these flocks do not migrate, their union is soon destroyed, for when the Black-cap Titmice again appear, it is in small flocks; their former restlessness is gone, and they now exhibit their wonted care and deliberation in searching for food.”
