Ruby-crowned Kinglet

Ruby-crowned Kinglet, Regulus calendula

A very small, olive-green bird with prominent white eyerings and white wingbars, the Ruby-crowned Kinglet can be found throughout most of North America. Although migratory with breeding grounds mainly in parts of Canada and Alaska, some live year round in parts of the western United States and Canada. The bright red crest of males which gives this kinglet its common name normally remains hidden unless provoked.

Ruby-crowned kinglets are mainly insectivores, but often eat some berries, seeds, and sap during winter. They can be found within trees and brush as well as isolated trees within meadows, but coniferous forests are a preferred habitat. Although tiny, the Ruby-crowned Kinglet lays a very large clutch of up to twelve eggs within a single nest. The red crown of the males is often visible during courtship displays. While monogamous during breeding season, they change mates each year.
