Ruby-crowned Kinglets are gleaners that eat small insects and spiders, but will also eat fruit and seeds during the winter or when invertebrates are not available.

Distribution 4

The Ruby-crowned Kinglet breeds across Alaska, Canada, and the northern tier of the United States. In the west, this species’ range extends south at higher elevations as far as southern Arizona. In winter, most populations migrate south to the southern half of the U.S., along the Pacific coast from British Columbia to California, and in Mexico, although some populations breeding in the mountain west simply winter at lower altitudes nearby.
