Ruby-crowned Kinglet (Regulus calendula)
Marianne Williams Park
Boise, Idaho
The Ruby-crowned Kinglet, one of North America's smallest songbirds, has a loud, complex song and, with up to 12 eggs, lays the largest clutch of any North American passerine for its size. Males and females are nearly identical in plumage -- olive green-gray on the upperparts with two strong white wing-bars and a broken, white eye-ring. The male has a scarlet crown patch, which is usually concealed unless agitated.
During migration and winter, the Ruby-crowned Kinglet occupies a variety of habitats and is often recognized by its constant wing-flicking. As a breeder, it inhabits spruce-fir forests of the northern and mountainous western United States and Canada. Its nest is hidden, often near the trunk and up to 30 meters above the ground, making reproductive data difficult to gather. Much remains to be learned about the breeding biology and behavior of this species.
