The delightful Ruby-crowned Kinglet is a small passerine or perching bird. Kinglets, like real kings, have a crown, although when it comes to the Ruby-crowned Kinglet you can't always see it. In fact, the female doesn't have a crown at all and it's often hidden on the male.
The Ruby-crowned Kinglet's range extends throughout North America. Except for the crown, the sexes are similar: white eye-rings; olive-greenish plumage; and two white wing bars. Favourite foods include insects, seeds and fruits.
