Of the twenty species of nuthatches known to inhabit the temperate regions of the Northern hemisphere, but four are distinctively American. They are classed by ornithologists with the tits and chickadees in the family Paridæ, a word derived from the Latin parus, meaning a titmouse. The nuthatches, like the woodpeckers, are climbers, but unlike the latter they climb downward as well as upward and with equal facility. Their tails are very short and are not used for support. Their bodies also do not touch the tree “unless they are suddenly affrighted, when they crouch and look, with their beaks extended, much like a knot with a broken twig to it.” A sudden clapping of the hands or a sharply spoken word will often cause a nuthatch to assume this attitude. They are busy birds, yet they are seldom too absorbed in their work of gathering food to stop and closely scrutinize an intruder. “Few birds are easier to identify: the woodpecker pecks, the chickadee calls ‘chickadee,’ while the nuthatch, running up and down the tree trunks, assumes attitudes no bird outside of his family would think of attempting.” They do not always seek their food in the crevices of the bark of trees but, flycatcher-like, will fly outward from their perch and catch insects on the wing. Mr. James Newton Baskett relates the following interesting observation: “One spring day some little gnats were engaged in their little crazy love waltzes in the air, forming little whirling clouds, and the birds left off bark-probing and began capturing insects on the wing. They were awkward about it with their short wings and had to alight frequently to rest. I went out to them and so absorbed were they that they allowed me to approach within a yard of a limb that they came to rest upon, where they would sit and pant till they caught their breath, when they went at it again. They seemed to revel in a new diet and a new exercise.” The Brown-headed Nuthatch is abundant from Louisiana and Florida to the southern part of Maryland. It also strays, at times, farther north, for it has been taken in Illinois, Michigan and Ohio. In the pine woods of the Southern States it passes a happy existence, always chattering in bird language even when its head is downward. “Each one chatters away without paying the slightest attention to what his companions are saying.” Mr. Chapman says: “There is such a lack of sentiment in the nuthatch’s character, he seems so matter-of-fact in all his ways, that it is difficult to imagine him indulging in anything like a song.” Though these words have reference to another species, they apply equally well to the Brown-headed form, whose only note seems to be a monotonous and oft-repeated utterance of a single syllable.
