Red-breasted Nuthatch (Sitta canadensis) - local seasonal appearance

Based on 6 observations in Seymour township, Northumberland county, southeast Ontario, 1999-2012.

The red-breasted nuthatch appears to be a relatively rare bird here, based on a sparse six sightings in 14 years. The apparent scarcity relative to the white-breasted nuthatch may in part be due to feeding habits: the red-breasted may spend less time on tree trunks where, like other nuthatches, creepers and woodpeckers, a bird may more readily be detected. It prefers the thicker growth of spruce crowns and branch ends where it is harder to see. Its fainter call may also be heard less often than the more strident white-breasted species. A preference for conifers as opposed to hardwoods (Cadman et al., 1987, pp.298-299) is a further reason why the red-breasted form may be more abundant north of our area. It does appear to be expanding southwards and probably breeds here (Cadman et al., 2007, pp.406-407), so perhaps this small but attractive bird will be seen more in the future.

The red-breasted nuthatch breeds at Presqu'ile provincial park, roughly 40 km to the south. It is an uncommon year-round resident but is most often seen in migration, during southward irruptions in the autumn. Highest spring counts are in April. "A small number breed annually but are difficult to find" (LaForest, 1993, p.260). The fall migration peaks in October.

In Peterborough county, to the northwest, this bird is resident all year, though some of the population migrate. The bird may be very common in some winters, as on the 1978 Christmas Bird Count. It nests widely in the northern part of the area, and also in the south. Concerning the more abundant white-breasted nuthatch, "This species seems to prefer tree trunks for hunting, while (the red-breasted nuthatch) is commonly found on the branches, especially those of conifers" (Sadler, 1983, p.117).
