278. Sitta uralensis

278. Subsp. Sitta uralensis.
Sitta uralensis, Licht. in Ginger’s, Handb. Vogel, Deutschl, pp. 377, 388 (1834) ; Gadow, Cat. B. Br. Mus. viii. p. 342 ; Tacz. F. O. Sib. O. p. 199 ; S. asiatica, Temm. Gould, B. of E. iii. pl. 236.
Male ad. (Siberia). Differs from 8. europoea in having the under parts purer white, and less chestnut on the flanks, the hoary margin bordering the upper part of the black ocular stripe more distinct and is as a rule smaller. Culmen 0.67, wing 3.25, tail 1.8, tarsus 0.75 inch.
Hab. Siberia, south to Lake Baikal, and Japan.
This subspecies varies according to locality, and has been considerably subdivided by those ornithologists who go in for splitting. Western specimens are, as a rule, the largest, and approach nearest to true Sitta europoea. Taczanowski makes two subspecies, Sitta baicalensis and Sitta. albifrons of the form inhabiting Siberia, the former of which I take to be true S. uralensis, as he describes it, as having no white on the forehead, and the latter, which has the forehead and superciliary stripe white, is the form found in Japan.
In habits and nidification this bird does not differ from S. europoea.
