Excerpts Adapted from the Birds of Saskatchewan:

"Although it is named for the bright, but usually concealed, crown feathers of the male, the king-sized song of this pint-sized songster helps to merit its regal surname ? (Smith 1996). One of North America's smallest songbirds, males arrive early, with females arriving later. Breeds across the boreal forest from Alaska to Newfoundland and south into mountainous western US. Winters across the southern US to southern Mexico.

The Ruby-crowned Kinglet is a common breeding bird in a wide variety of coniferous and mixedwood forests, but perhaps most abundant in the tracts of black spruce in the subarctic and in cold bogs farther south. The tops of the conifers provide nesting habitat as well as food sources. As a migrant the Ruby-crowned Kinglet frequents all types of forest and woodland both natural and planted.

These birds are common in the subarctic, the boreal forests, and the Cypress Hills (Smith 1996). They are common to uncommon transients throughout the southern half of the province, except when they occasionally breed in planted conifers in the cities of Saskatoon (Mary Gilliland) and Regina (Trevor Herriot in Koes and Taylor 1996d).
