Most of the time, a Ruby-crowned Kinglet is neither ruby nor regal. A tiny songbird washed in faded olive-green, the male shows a hint of crimson atop of his head — hardly a ruby crown. But don’t forsake the kinglet for flashier birds. When courting a female or dueling with another male, the kinglet exposes those ruby feathers, and his crown glows with the feathery fireworks that give the bird its name. Now is the time to look for kinglets, as they migrate north across much of the continent toward breeding sites in remote evergreen woods. Learn more at BirdNote.org.
