The Ruby-crowned Kinglet was described in 1766 by Linnaeus; its generic name is Latin for 'little king'. It differs sufficiently in its voice and plumage from other kinglets that it is occasionally afforded its own genus, Corthylio.

They feed lower in the canopy than the Golden-crowned and characteristically hovers above a twig looking for caterpillars, aphids, and other insects.

A group of kinglets has many collective nouns, including a "castle", "court", "princedom", and "dynasty" of kinglets.
The Ruby-crowned Kinglet is a small songbird found throughout North America. Typical breeding habitats of this bird include coniferous woodlands in Canada, Alaska, northern New England and the western United States.



Nests are cup-shaped and suspended from branches on the conifers. In winter months, this species migrates southward to the southern United States and Mexico. Some western populations are permanent residents.

Recently, less disturbed populations have been discovered farther north. This species forages for food in trees and shrublands, eating insects, spiders, berries and tree sap. The conservation rating for the Ruby-crowned Kinglet is Least Concern.
