This Nuthatch was observed by Mr. Ridgway among the aspen groves bordering the streams that flow from the East Humboldt Mountains. In that locality it was common through the month of September, though not abundant. It was again seen in June among the pine-woods of the Wahsatch Mountains, but it was not common.
While a few of these birds are resident of the Northern States, they are, to a considerable extent, of migratory habits. Wilson observed them leaving in large numbers for the Southern States in October, and returning again in April. On the 20th of May, 1867, the writer observed a small flock in Eastern Massachusetts, evidently just arrived from the South. They were apparently fatigued and hungry, and paid no attention to the near presence of workmen engaged in setting bean-poles. They visited and carefully examined each pole, and bored holes into several in search of hidden larvæ, often within a few feet of persons at work.
While on the Pacific coast they are said to prefer the forests of deciduous trees, and to be rarely found in the dark evergreen forests, in the Eastern States they seem to be particularly fond of the seeds of pine-trees, and in the winter are seldom found in the woods of deciduous trees.
They feed in pairs and climb about in all directions, usually in company with the white-breasted species, Chickadees, and the smaller Woodpeckers. They are restless and rapid in their motions, and have a voice at least an octave higher than any other of this family. The note is a monotone, and is unmusical. Mr. Nuttall represents their cry as consisting of three syllables, represented by dāy-dāy-dāit, and compares it to the sound of a child’s trumpet.
Those wintering at the North occasionally visit farm-yards and orchards, and examine the eaves of outbuildings for food.
Audubon found this species more plentiful in the woods of Maine and Nova Scotia than anywhere else. He never met any south of Maryland, saw none in Newfoundland, and only met with one in Labrador. At Eastport he found a pair breeding as early as the 19th of April, before the Bluebirds had made their appearance, and while ice was still remaining on the northern exposures. An excavation had been made in a low dead stump, less than four feet from the ground, both male and female birds working by turns until they had reached the depth of fourteen inches. The eggs, four in number, were of a white ground-color, tinged with a deep blush when fresh, and sprinkled with reddish dots. They raise but a single brood in a season.
C. S. Paine, of East Bethel, Vt., found a nest of this species about the middle of May, in a small beech-tree, the excavation having been made at the height of twelve feet from the ground. The hole was about as large as that made by the Downy Woodpecker. When first noticed, the bird was looking out of the hole. Having been started out, she flew to a limb close by and watched the party some time. When she flew back, she buzzed before the hole in the manner of a Humming-Bird, and then darted in. While Mr. Paine was looking on, the male came several times to feed his mate, who would meet him at the opening with a clamorous noise, to receive his bounty. The nest contained five eggs.
In Western Massachusetts, Mr. Allen speaks of this species as chiefly a winter resident, appearing the first week in October, and leaving the last of April.
The eggs of this species measure .62 by .48 of an inch, and are of an oblong-oval shape. Their ground-color is a clear crystal white, marked principally about the larger end with a wreath of purple and roseate markings.

Sp. Char. Above ashy-blue; head and upper part of neck greenish ashy-brown, its lower border passing a little below the eye, where it is darker; nape with an obscure whitish spot. Chin and throat whitish; rest of lower parts brownish-white; the sides and behind like the back, but paler. Middle tail-feather like the back; its basal half with a long white spot; its outer web edged with black at the base. Length about 4 inches; wing, 2.40.
Hab. Western and Middle Provinces of United States; south to Xalapa.
This species is closely related to Sitta pusilla of the Southern States. The brown of the head has, however, an olivaceous-green tinge not seen in the other; the white spot on the nape less distinct. The middle tail-feather has its basal half white and the outer web edged with black at the base. This black edging is never seen in the other, and the white patch is reduced to a faint trace, only visible in very highly plumaged specimens.
Habits. This diminutive species of Nuthatch is found throughout our Pacific coast and on the western slope of the Rocky Mountains, from Washington Territory to Southern California. It is also to be found in New Mexico, and specimens have been procured from Mexico.
Dr. Kennerly found them quite abundant in the Sierra Madre and San Francisco Mountains, even as high up as the snow-line, seeking their insect food among the tops of the lofty pines. Dr. Newberry frequently met with these Nuthatches in the most wooded places on his route, where water was near and any considerable amount of animal life visible. He, however, never met with them in the forests of yellow pines. Dr. Gambel mentions their almost extraordinary abundance, in the winter months, in Upper California. Around Monterey, at times, the trees appeared almost alive with them, as they ran up and down and around the branches and trunks, uttering their monotonous and querulous cries. Their note he describes as a repeated whistling wit-wit. When one utters this cry, the rest join in. They also have a whistling trill while they are busily searching the tree in every part, and they never leave till they have pretty thoroughly searched every crack.
Dr. Cooper only met with this Nuthatch in the open pine-forests about Fort Colville, near the 49th parallel. They were associated in small flocks about the 20th of October, when there were heavy frosts at night. The chirping noise they made resembled the cries of young chickens. Their habits were very similar to those of the Psaltriparus minimus.
Mr. J. K. Lord found this Nuthatch an abundant bird along the entire length of the boundary line from the coast to the Rocky Mountains. It was also common on Vancouver Island. They were seen in large flocks in company with the Chickadees, except during the nesting-time, which is in June. A few were winter residents at Colville, but the greater number left in November. He describes it as a very active bird, always on the move. After nesting they congregate in large flocks and move about from tree to tree, twittering a low sweet note as if singing to themselves, now climbing back downwards along the under sides of the topmost branches of tall pines, searching into every crevice for insects, or, descending to the ground, clinging to the slender flower-stalks for other insects. They nest in June, make a hole in the dead branch of a pine, and deposit their eggs on the bare chips of the wood. This account does not agree with the experience of California ornithologists, who have found a loose nest within the excavation.
Mr. Ridgway found this Nuthatch abundant among the pines of the Sierra Nevada, in the vicinity of Carson City. They were found generally in pairs. Its note is said to greatly resemble the vociferous peeping of some of the small Sandpipers, being sharp, loud, and distinct, and vigorously and continuously uttered, whether climbing or flying. He found it exceedingly hard to discover this bird among the branches, or even when flying, owing to the swiftness and irregularity of its flight. When the female of a pair had been killed, the male bird was extremely loud in his lamentations. Diminutive as this bird is, Mr. Ridgway states that it is also the noisiest of all the feathered inhabitants of the pines, though it is less active in the pursuit of insects than the larger species.
Nests of this bird obtained near Monterey appear to be as well made as those of any of this genus, lining the cavity in which they are placed and conforming to it in size and shape, the materials sufficiently interwoven to permit removal and preservation, and warmly constructed of feathers, wool, vegetable down, hair, and the silky efflorescence of seeds.
