Nuthatches
Sitta canadensis
The Red-breasted Nuthatch is a small, active songbird recognized by its distinctive head pattern and rusty underparts. These birds are often observed moving headfirst down tree trunks and branches, a characteristic nuthatch behavior. They are primarily found in coniferous forests across North America.

Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
Features a prominent black eye stripe contrasted by a white eyebrow and a black cap.
Adults have buffy-orange to rusty-cinnamon underparts, which are typically paler in females.
The back and wings are a blue-gray color.
Possesses a straight, slender, and somewhat upturned gray bill.
02 / A place in the world
Red-breasted Nuthatches primarily inhabit coniferous and mixed coniferous-deciduous forests, favoring areas with spruce, fir, pine, and hemlock. They prefer mature forests with decaying wood for nesting. During winter, they may be found in a wider variety of wooded habitats, including deciduous trees.
This species breeds across Canada, Alaska, and the northern and western United States, extending south through the Appalachian Mountains. Its range includes southeastern Alaska, southern Yukon, central Quebec, and Newfoundland, south to northern California and the Great Lakes region.
While generally resident, Red-breasted Nuthatches are known for irregular southward irruptions in winter, especially when conifer cone crops are poor in their northern breeding grounds. These movements can cover hundreds of miles.
03 / Listen a little closer
Their calls are often described as a distinctive, high-pitched, nasal, and somewhat tinny series of notes. Males use a soft, musical song during courtship.
04 / The life behind the feathers
Their diet consists mainly of insects and spiders during the summer months. In winter, they shift to consuming conifer seeds, as well as seeds from other trees like beech and oak.
These nuthatches forage by gleaning insects and spiders from tree bark, often moving headfirst down trunks and branches. They may wedge larger seeds into bark crevices to break them open with their bills.
Both sexes excavate nest cavities in rotten wood, typically in dead stubs or snags, usually 1.5-12 meters above the ground. They line the cavity with soft materials like grass, moss, and bark fibers, and often smear sticky pitch around the entrance.
Red-breasted Nuthatches are active birds that cling to trees, moving up, down, and sideways along trunks and branches without using their tail for support. They can be quite bold and may approach humans closely. They are territorial during the breeding season.
One more reason to pay attention
The Red-breasted Nuthatch is the only North American nuthatch species known to regularly undertake significant migratory movements.
They smear sticky conifer resin around their nest hole entrance, possibly to deter predators or competitors.
This species is considered a 'weak' excavator, preferring softer, decaying wood for creating its nest cavities.
