The Ruby-crowned Kinglet is a very small passerine bird found throughout North America. The bird has olive-green plumage with two white wing bars and a white eye-ring. Males have a red crown patch, which is usually concealed. The sexes are identical, apart from the crown. It is one of the smallest songbirds in North America.
Fun Fact Often, they perform a "broken-wing" act to draw predators away from their nest, which they will defend fearlessly, mobbing the intruder which may be a cat, squirrel, or human.
