Diet and Foraging

There are virtually no specific data. This species is presumed to forage in a fashion similar to that of many nuthatches, and it is known to feed on the seeds of Siberian stone pine (Pinus sibirica) and presumably feeds on a variety of small arthropods as well.

The Siberian Nuthatch typically feeds singly or in pairs (7 Harrap, S., and D. Quinn (1996). Tits, Nuthatches & Treecreepers. Christopher Helm, London, UK. Close ), though it is known to feed in single-species flocks as well (18 Tomkovich, P. S. (2008). Birds of the upper Anadyr River (Chukotka Autonomous Area). Collection of Works of the Zoological Museum of Moscow State University, Number 49. Close ) and likely joins mixed-species flocks, as does the Eurasian Nuthatch (Sitta europaea), the White-tailed Nuthatch (Sitta himalayensis), and the Red-breasted Nuthatch (Sitta canadensis) during the non-breeding season (44 Morrison, M. L., K. A. With, I. C. Timossi and K. A. Milne. (1986). Composition and temporal variation of flocks in the Sierra Nevada. Condor 89:739-745. Close , 7 Harrap, S., and D. Quinn (1996).

Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors). Cornell Lab of Ornithology, Ithaca, NY, USA. Close ). Methods of foraging have not been specifically described, but this species likely forages by moving along tree trunks (often upside down) and branches while probing crevices in bark, beneath flakes of bark, and at the bases of needle clusters on conifers in search of arthropods, and by probing conifer cones for seeds as is common among nuthatch species such as the Siberian Nuthatch, the Red-breasted Nuthatch, the Pygmy Nuthatch (Sitta pygmaea), and the White-breasted Nuthatch (Sitta carolinensis) (46 McEllin, S. M. (1979b). "Population demographics, spacing, and foraging behaviors of White-breasted and Pigmy nuthatches in ponderosa pine habitat."

No specific data. Presumably the diet consists mostly of arthropods and conifer seeds (41 Harrap, S., J. del Hoyo, N. Collar, G. M. Kirwan, and D. A. Christie (2020). Eurasian Nuthatch (Sitta europaea), version 1.0. In Birds of the World (S. M. Billerman, B. K. Keeney, P. G. Rodewald, and T. S. Schulenberg, Editors). Cornell Lab of Ornithology, Ithaca, NY, USA. Close ).

No specific data. The Siberian Nuthatch probably stores seeds in bark crevices and other similar locations for later use, as do many other nuthatches, such as the Eurasian Nuthatch, Red-breasted Nuthatch, and the Pygmy Nuthatch (48 Stallcup, P. L. (1968). Spatio-temporal relationships of nuthatches and woodpeckers in ponderosa pine forests of Colorado. Ecology 49:831-843. Close , 49 Kilham, L. (1974c).
