The ruby-spotted wood warbler ( Leiothlypis ruficapilla ) is a small insectivorous bird in the wood warbler family (Parulidae).
features
Ruby-blotch warblers have olive-green to olive-brown plumage on the upper side, and white-yellow on the underside with yellow belly and chest plumage and a yellow throat. There is a white ring around the black eyes. The male's head is gray and has a rust-colored to pale red crown spot, which, however, is embedded in the head plumage in such a way that it is often not visible. The female and the young birds have duller gray plumage on the head. Their legs are black.
nutrition
They feed mostly on insects that they find in the lower regions of the trees and bushes. Outside the breeding season, they add berries and seeds to their diet.
Reproduction
The females lay their bowl-shaped nests, which are open at the top, well hidden in the thicket under bushes or in the high vegetation. The female lays four to five brown-spotted white eggs in the nest, which it hatches after about eleven to twelve days. During the breeding season, the female is provided with food by the male. Both parent animals take part in the rearing of the young birds.
Occurrence
Ruby-spot warbler breed in mixed deciduous forests or near swamps in the northwest and west of North America , such as Canada . In winter, they migrate to southern Texas , Mexico, and Central America .
