Sitta carolinensis
| Conservation status | Widespread and common, with numbers stable or possibly increasing. |
|---|---|
| Family | Nuthatches |
| Habitat | Forests, woodlots, groves, shade trees. Typically in mature deciduous forest, also in mixed forest with some conifers; rarely found in pure coniferous forest. Often favors woodland edge, along rivers, roads, clearings; may be in suburbs or parks as long as large trees are present. |
Forages mainly on trunk and larger limbs of trees, climbing about and exploring all surfaces. Sometimes feeds on ground. During fall and winter, regularly caches food items in bark crevices on territory.
5-9, rarely 10. White, spotted with reddish-brown. Female incubates, is fed on nest by male. Incubation period 12-14 days. Young: Both parents feed young. Age when young leave nest uncertain, or perhaps quite variable; reported as 14-26 days. 1 brood per year.

Mostly insects, also seeds. Eats mostly insects (and spiders) during summer, supplementing these with seeds in winter. Proportion of seeds in diet may vary from zero in summer to more than 60% in winter. Will also feed on suet and peanut-butter mixtures at feeders. Young are fed entirely on insects and spiders.
Pairs remain together on nesting territory all year, may mate for life. Courtship behavior begins by late winter. In courtship display, male raises head, spreads tail, droops wings, sways back and forth, and bows deeply. Male also performs much courtship feeding of female. Nest site is large natural cavity or old woodpecker hole, usually 15-60' above ground; may rarely use birdhouses; may sometimes excavate own nest cavity. Female builds nest in cavity, a simple cup of bark fibers, grasses, twigs, hair. Adults may spend minutes at a time sweeping the outside and inside of nest with a crushed insect held in bill; chemical secretions of insects may help repel predators. Also sometimes adds mud to rim of nest entrance.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
New studies suggest that northern populations of White-breasted Nuthatches might also have irruptive years—and 2020 is one of them.
Migratory species that zip through the woods for insects are more likely to crash, researchers find—a vulnerability that may be speeding their decline.
It took a pandemic for me to see what my mother had been trying to show me my whole life.
