The Ruby-Crowned Kinglet: A Tiny Gem of North America
The ruby-crowned kinglet (Corthylio calendula) is a very small passerine bird often recognized for the distinctive red patch found on the head of the male. These active birds are common throughout North America and belong to the kinglet family, known for their diminutive size and energetic movements.
Key Features and Appearance
Despite its small stature, the ruby-crowned kinglet possesses several notable characteristics that help identify it:
- Plumage: Its body is predominantly olive-green, providing excellent camouflage among foliage.
- Wing Bars: Two prominent white wing bars are visible on its wings, contrasting with its darker feathers.
- Eye-ring: A subtle white eye-ring encircles its eyes, adding to its delicate appearance.
- Red Crown Patch: The most striking feature, particularly on the male, is a vibrant red crown patch. This patch is often concealed, only becoming visible when the bird is agitated, singing, or displaying, giving the impression of a "red circle" on its head.
- Size: As one of the smallest North American songbirds, its compact size further emphasizes its unique markings.
