Their eggs, seven in number, resemble those of the _S. canadensis_, but are of smaller size and a little more pointed at one end. Their ground-color is crystalline-white. This is covered more or less thickly with red spots, most numerous at the larger end. Their measure varies from .65 by .50 to .60 by .47 of an inch. The first eggs of this bird brought to the notice of naturalists were procured at Fort Crook on the Upper Sacramento of California, and not far from Mount Shasta, by Sergeant John Feilner, U. S. A., forming part of a very extensive collection of birds and eggs transmitted by him to the Smithsonian Institution. Promoted to a lieutenancy for gallant conduct, this gentleman finally attained the rank of captain of cavalry, and was killed by the Sioux during an exploring expedition into Dacotah under General Sully.

KIRTLAND. HABITS. The Brown-headed Nuthatch has a much more restricted distribution than the other members of this family in this country. The specimens in the Smithsonian Museum are chiefly from Georgia. Wilson met with it in Virginia, and states that it is found in the other Southern States. I have received its eggs from Cheraw, S. C., and from Florida. Wilson’s description of its habits makes them almost identical with those of _Sitta canadensis_, while its notes are more shrill and chirping. Like that bird, it is very fond of the seeds of the pines. Wherever found, it is a constant resident, and does not migrate. Audubon states that this bird never goes farther north than Maryland, and that it is the most abundant in Florida, Georgia, and the Carolinas. In Louisiana it is rare, and it is not found in Kentucky. Its notes, he states, are several octaves higher than those of the _carolinensis_, and more shrill, and at least an octave and a half higher than those of the _canadensis_.
