Sitta carolinensis

Bears a superficial resemblance to S. leucopsis and S. przewalskii, but most recent genetic study recovered the present species as sister to S. magna#R. Geographical variation relatively slight and largely clinal, upperparts (and, to lesser extent, underparts) on average darkest in Rocky Mts and Mexico, becoming paler towards W and especially E coasts; race alexandrae sometimes merged with tenuissima, and oberholseri with nelsoni; population in NE of range (E Canada and NE USA) sometimes separated as race cookei, with slightly paler back, and with most females pale-capped, but differences from nominate clinal and/or not constant. However, molecular phylogenies based on mitochondrial and nuclear datasets have recovered clear evidence of four geographical groupings: (1) E North America, (2) S Rocky Mts and Mexican mountains, (3) E Sierra Nevada and N Rocky Mts and (4) Pacific slope of North America#R#R. Proposed race atkinsi from SE USA (Tarpon Springs, in Florida) synonymized with nominate, and N Mexican umbrosa (from Sierra Madre near Guadalupe y Calvo, in SW Chihuahua) with mexicana, within which kinneari is sometimes also subsumed. Nine subspecies recognized.
