species collect and store away the fruit of the hazel and other nut-bearing trees. Our bird has been supposed to do the same thing, but this is by no means an indisputable fact.
In some parts of the country absurd prejudices prevail against these interesting little birds. They are indiscriminately confounded with the smaller Woodpeckers, called, with them, Sap-Suckers, and because in the spring and fall they frequent old orchards are most unwisely, as well as unjustly, persecuted. They are among the most active and serviceable of the fruit-grower’s benefactors. His worst enemies are their favorite food. It is to be hoped that soon a better-informed public opinion will prevail, cherishing and protecting, rather than seeking to destroy, this useful, affectionate, and attractive species.
Interesting accounts are given in English works of the confiding tameness of the European species. When kindly treated, it will come regularly for its food, approaching within a foot or two of the hand of its benefactor, and catching with its bill the food thrown to it before it can reach the ground.
The pair work together in constructing the perforation in which they make their nest. When the excavation has been well begun, they relieve each other at the task. The one not engaged in cutting attends upon its mate, and carries out the chips as they are made. These nesting-places are often quite deep, not unfrequently from fifteen to twenty inches. Audubon states that they build no nest, but this does not correspond with my observations. In all the instances that have come to my knowledge, warm and soft nests were found, composed of down, fur, hair, or feathers loosely thrown together, and, though not large in bulk, yet sufficient for a lining for the enlarged cavity that completes their excavation. Soon after they are hatched, the young climb to the opening of the nest to receive their food, and, before they are ready to fly, venture out upon the trunk to try their legs and claws before their wings are prepared for use, retiring at night to their nest. In the Southern States they are said to have two broods in a season.
The eggs of this Nuthatch measure .80 by .62 of an inch. Their ground-color is white, but when the egg is fresh it has a beautiful roseate tinge, and generally receives an apparently reddish hue from the very general distribution of the spots and blotches of rusty-brown and purplish with which the eggs are so closely covered. These markings vary greatly in size, from fine dots to well-marked blotches. Their color is usually a reddish-brown; occasionally the markings are largely intermixed with purple.

Sp. Char. Very similar to carolinensis; but upper secondaries with only obscure blackish blotches, instead of sharply defined longitudinal spots of clear black. Bill slenderer and more attenuated.
Hab. Western and Middle Provinces of the United States, south to Cordova, Mex. Orizaba (Alpine regions), Sumich.
The characters given above express the essential differences between this and the Eastern race of S. carolinensis. In the present form, the depth of the bill opposite its base is .14, the width .17, and .80 or more in length from the forehead; while these same measurements in var. carolinensis are .17, .22, and .70. The obsolete character of the black spots on the secondaries is a persistent feature in the var. aculeata.
Habits. This bird chiefly differs from its eastern congener in its more slender bill. There appears to be no difference in regard to their habits, at least none have been noticed, and it is probable there is none other than trivial changes caused by its opportunities of procuring food, and the kinds upon which it subsists. It is supposed to be distributed throughout Western North America, from the British Possessions to Mexico, though Dr. Cooper thinks that it is not a common bird south of San Francisco, and only to be seen there in the colder months. It has been met with at San Diego in February. He did not observe any in the Coast Mountains, near Santa Cruz, but northward they are numerous in the summer, frequenting chiefly the groves of the deciduous oaks, creeping constantly about their trunks and branches in search of insects, which they also occasionally seek on the roofs and walls of houses. Their habits are similar to those of S. canadensis, but their movements are said to be slower, and their note is a single harsh call, uttered occasionally, and responded to by their comrades. Dr. Cooper found them quite common in Washington Territory and at Puget Sound. Dr. Suckley also mentions their great abundance.
Dr. Kennerly met with this species a hundred miles west of Albuquerque, New Mexico, and quite abundant among the pines of the Sierra Madre. He speaks of its note as being peculiar.
Mr. J. K. Lord states that this species remained about Colville during the winter, when the thermometer was 30° below zero. He also mentions that he found them nesting, in June, in the branches of the tallest pine-trees, so high up as to render the obtaining their eggs almost an impossibility.
Mr. Ridgway found the Slender-billed Nuthatch abundant, throughout the year, in the vicinity of Carson City, among the pines on the Sierra Nevada Mountains. He noted its great similarity in manners to the carolinensis; at the same time the well-marked difference in the notes did not escape his attention. These notes are much weaker, and are uttered in a finer tone, and some of them are said to be entirely different.

Sp. Char. Above ashy-blue. Top of head black; a white line above and a black one through the eye. Chin white; rest of under parts brownish-rusty. Length about 4.50 inches; wing, 2.66. Female with the black of head mixed with ashy; beneath paler, more of a muddy-white.
Hab. Whole United States and British Provinces. North to Lake Winnipeg.
Habits. The common Red-bellied Nuthatch, though nowhere a very abundant species, is found throughout the whole of North America, from Florida to high northern regions, and from ocean to ocean. The Smithsonian Institution possesses specimens from Georgia, Selkirk Settlement, California, and Washington Territory. Mr. Gambel found them quite common in the mountains in the interior of California, in October, roving in company with busy flocks of the Parus montanus.
Dr. Cooper met with them abundantly in Washington Territory, where they preferred the oaks and other deciduous trees, and never frequented the interior of the dense forest. He observed this bird and the Slender-billed Nuthatch, along the 49th parallel, east of the Cascade Mountains, as late as the middle of October. Dr. Suckley also met both birds west of the same mountains.
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.
