The Ruby-crowned Kinglet is a tiny, olive-green bird that flicks its wings nervously and constantly — a distinctive behavioral hallmark. The male's ruby crown patch is usually concealed but flashes brilliantly when the bird is excited or alarmed. Despite its minuscule size, it produces an astonishingly loud and complex song that can carry over a large area.
