A tiny bird bursting with energy, the Ruby-crowned Kinglet (Corthylio calendula) darts through the lower branches of shrubs and trees in constant motion. Rarely still, it flits from twig to twig, flicking its wings in a way that gives it a distinctly restless, almost nervous appearance.

Among North America’s smallest songbirds, Ruby-crowned Kinglets measure just 3.5 to 4.3 inches long. Their olive-green plumage, short tails, and fine bills add to their delicate look. Males sport a vivid ruby crown that’s usually hidden but raises when agitated or excited. Females can lay a very large clutch of eggs, up to 12 in a single nest.

These lively birds feed on a variety of insects, including aphids, wasps, ants, and bark beetles. Their constant wing-flicking may even help flush prey from hiding. At Moorhen Marsh, abundant food and safe habitat make it an ideal haven for Ruby-crowned Kinglets and a fitting place to tip our crowns in welcome.
