SITTA CANADENSIS, Linn. 
Red-bellied Nuthatch. 
Sitta canadensis, Linn. Syst. Nat. I, 1766, 177.— Nuttai.l, Man. I, 1832, 583 .—Aud. Orn. Biog. II, 1834, 24: V,

Sitta varia, Wils. Am. Orn. I, 1808, 40 ; pi. ii. 
Sitta stulta, Vieill. Nouv. Dict.(?) 
Sp. Ch.— Above ashy blue. Top of head black ; a white line above and a black one through the eye. Chin white ; rest of 
under parts brownish rusty. Length about 4^ inches; wing, 2§. 
Hab. —North America to the Rocky mountains. Probably also to the Pacific. 
Fourth quill longest; third a little shorter, hut longer than fifth ; second intermediate 
between sixth and seventh. Above ashy blue. Top of head from hill to occiput deep black ; 
sides of head and chin white, with a narrow black band from the bill through the eye ; under 
parts generally yellowish rusty, deepest towards the tail. Under wing coverts tinged with 
black. Wing feathers brown, edged with the color of the back, and without white or black 
marking. Tail feathers narrowly tipped with bluish ; central one like the black ; rest of 
feathers black ; the first and second with a subterminal, the third with a terminal bar of white. 
The female has the black of the head tinged with dark ash ; the under surfaces lighter, more 
of a muddy white. 
I am unable to detect any difference between eastern and western specimens. One of the latter 
(6839) has the bill much stouter than any others I have seen from either side of the continent, 
being quite as broad at the base as in a much larger S. carolinensis from Pennsylvania. 
The rusty belly and white streak over the eye, with the black one through it, will readily 
distinguish this from any other North American species.
