Its range is primarily in the arid southwestern U.S. and Mexico, with little overlap in breeding areas with the Blue-gray Gnatcatcher.

Kinglets are slightly chunkier, have shorter tails, and lack the prominent white eye-ring and extensive white in the tail. They also have a different foraging style and vocalizations. The Ruby-crowned Kinglet male has a red crown patch, which is usually concealed.
