IUCN Conservation Status: Least Concern
One of North America's smallest birds, the Ruby-crowned Kinglet can be recognized by its constant wing-flicking. The male shows its red crown only infrequently.
Song a jumble of notes, starting with two or three high "tsees," followed by five or six lower "tur" notes, and ending with repeated "tee-da-lett" phrases.
Call a quick "di-dit."
