Sitta carolinensis
Like other members of its genus, the White-breasted Nuthatch has a large head, short tail, short wings, a powerful bill and strong feet; it is 13–14 cm (5–6 in) long, with a wingspan of 20–27 cm (8–11 in) and a weight of 18–30 g (0.64–1.06 oz). The adult male of the nominate subspecies, S. c. carolinensis, has pale blue-gray upperparts, a glossy black cap (crown of the head), and a black band on the upper back. The wing coverts and flight feathers are very dark gray with paler fringes, and the closed wing is pale gray and black, with a thin white wing bar. The face and the underparts are white. The outer tail feathers are black with broad diagonal white bands across the outer three feathers, a feature readily visible in flight. The female has, on average, a narrower black back band, slightly duller upperparts and buffer underparts than the male. Her cap may be gray, but many females have black caps, and cannot be reliably distinguished from the male in the field. In the northeastern United States, at least 10% of females have black caps, but the proportion rises to 40–80% in the Rocky Mountains, Mexico and the southeastern U.S. Juveniles are similar to the adult, but duller plumaged. Like other nuthatches, this is a noisy species with a range of vocalizations. The male's mating song is a rapid nasal "qui-qui-qui-qui-qui-qui-qui." The contact call between members of a pair, given most frequently in the fall and winter is a thin squeaky nit, uttered up to 30 times a minute. A more distinctive sound is a shrill kri repeated rapidly with mounting anxiety or excitement "kri-kri-kri-kri-kri-kri-kri-kri"; the Rocky Mountains and Great Basin subspecies have a higher, faster "yididitititit" call, and Pacific birds a more nasal "beeerf." Three other, significantly smaller, nuthatches have ranges which overlap that of White-breasted, but none has white plumage completely surrounding the eye. Further distinctions are that the Red-breasted Nuthatch has a black eye line and reddish underparts, and the Brown-headed and Pygmy Nuthatches each have a brown cap, and a white patch on the nape of the neck.

This was spotted at my mother's feeder. I'll be visiting again soon and will hopefully get better images.
