Life history

How this bird lives

Habitat and nesting

Bluebirds use existing cavities rather than excavating their own. The female builds a grass-lined nest after the pair selects a site. [2]

Food and foraging

Insects and seasonal fruit. [2]

Watch where the bird searches for food and how it moves. Feeding behavior can be a useful clue alongside plumage.
