"When I see him sitting quite still for a few moments on a branch of a tree in his most characteristic nuthatch attitude, on or under the branch, perched horizontally or vertically, with head or tail uppermost, but always with the body placed beetle-wise against the bark, head raised, and the straight, sharp bill pointed like an arm lifted to denote attention,--at such times he looks less like a living than a sculptured bird, a bird cut out of beautifully variegated marble--blue-gray, buff, and chestnut, and placed against the tree to deceive the eye. The figure is so smooth and compact, the tints so soft and stone-like; and when he is still, he is so wonderfully still, and his attitude so statuesque! But he is never long still and when he resumes his lively, eccentric, up-and-down and sidewise motions, he is interesting in another way. He is like a small woodpecker who has broken loose from the woodpecker's somewhat narrow laws of progression, preferring to be a law unto himself. "Without a touch of brilliant color, the nuthatch is a beautiful bird on account of the pleasing softness and harmonious disposition of his tints; and, in like manner, without being a songster in the strict sense of the word, his voice is so clear and far-reaching and of so pleasing a quality, that it often gives more life and spirit to the woods and orchards and avenues he frequents than that of many true melodists. This is more especially the case in the month of March, before the migratory songsters have arrived, when he is most loquacious. A high pitched, clear, ringing note, repeated without variation several times, is his most often-heard call or song. He will sometimes sit motionless on his perch, repeating this call at short intervals, for half an hour at a time. Another bird at a distance will be doing the same, and the two appear to be answering one another. He also has another call, not so loud and piercing, but more melodious: a double note, repeated two or three times, with something liquid and gurgling in the sound, suggesting the musical sound of lapsing water. These various notes and calls are heard incessantly until the young are hatched, when the birds at once become silent."
