These charming birds are relatively abundant and widespread throughout North America and are a quite underappreciated bird. Here in the west, they are generally only found in or around coniferous forests and pineland savannas, whereas their eastern cousins are a much more urban or suburban bird. Their song is a loud trill which, often to the chagrin of field ornithologists, varies substantially among individuals and can easily be confused with the trills of Dark-eyed Juncos, towhees, and many species of warblers.
