Corthylio calendula

The Ruby-crowned Kinglet is a tiny, active songbird that breeds mainly in northern and mountain conifer forests. It searches foliage almost continuously, often flicking its wings as it picks small insects from leaves and twigs. The male's red crown patch is usually hidden and may be raised during display or agitation.
