Bluebird nests are built by the female, usually in a cavity created by another bird or in an artificial birdhouse. Bluebirds have weak bill so they cannot carve out their own cavities. It takes two to five days of hard work for the nest to be completed. Bluebird nests are light and delicate–consisting of grasses, hair fibers, feathers and needles.
The bird has a round belly, long wings, and short legs. Its black bill is short and straight. Male eastern bluebirds are easily identified by their bright blue heads and wings. Females sport duller colors, with grayish heads and backs and bluish wings. Both males and females have a rust-colored throats and white stomachs.
