Ruby-crowned kinglet

Regulus calendula

The ruby-crowned kinglet is a very small passerine bird found throughout North America. It is a member of the kinglet family. 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, and juveniles are similar in plumage to adults.

I admit that I know very little about birds, but this is another bird that was new to me...never even heard of it before. I saw several other interesting birds today, but didn't get shots of most of them...I predict that I will pay closer attention to birds in the future.

Appearance

The ruby-crowned kinglet is a very small bird, being 9 to 11 cm long, having a wingspan of 16 to 18 cm, and weighing 5 to 10 g. It has gray-green upperparts and olive-buff underparts. It has two white wingbars and a broken white eye ring. The wingbar on the greater secondary coverts is wider, and is next to a dark band.

The kinglet has a relatively plain face and head, although the male has a scarlet-red crown patch, which is usually concealed by the surrounding feathers. The crown patch is rarely orange, yellow, or not present. Females are identical to males. Immature birds are similar to adult females, since young males lack a crown patch.

Distribution

Their breeding habitat is coniferous forests across Canada, Alaska, northern New England and the western United States. They nest in a well-concealed hanging cup suspended from a conifer branch and may lay as many as twelve eggs in a clutch.

Status

The recent counting indicates that the ruby-crowned kinglet population is on the rise. This is mainly due to discovery of less disturbed territory farther north. This allows more successful breeding.

Behavior

The kinglet usually moves along branches or through foliage with short hops, and flies with bursts of rapid wing beats. It is constantly active, and is easily recognized by its characteristic wing-flicking. Its flight has been described as "swift, jerky, and erratic".

Ruby-crowned kinglets forage actively in trees or shrubs, mainly eating small insects and spiders, some berries and tree sap. They may hover over a branch while feeding and sometimes fly out to catch insects in flight. The red crest is raised when agitated or in display. 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.
