kinglet
A very small, active songbird with a bright crown patch.
A kinglet is a very small songbird, among the tiniest birds in North America. These active little birds weigh less than a pencil and rarely sit still, constantly flitting through trees searching for insects and spiders to eat. Despite their tiny size, kinglets survive harsh winters that drive larger birds south, thanks to their thick, fluffy feathers.
The two species found in North America are the ruby-crowned kinglet and the golden-crowned kinglet, named for the colorful patches on their heads. Male ruby-crowned kinglets can flash brilliant red crown feathers when excited or defending territory, though they usually keep them hidden. Golden-crowned kinglets sport bright yellow and orange stripes year-round.
The name kinglet means “little king,” referring to these crown-like markings. When you spot a kinglet, you might first notice its high-pitched calls or the constant movement of a tiny bird hovering near branch tips. Though small enough to hold in your palm, kinglets are remarkably tough, enduring freezing temperatures and flying thousands of miles during migration. Birdwatchers love the challenge of spotting these energetic kinglets as they zip through forest canopies.
The word can also describe a minor ruler or someone with limited authority, like calling someone the kinglet of a small domain.
