It, too, has a red breast but a blue throat and rusty back. It s found west of the Rockies and from the Canadian border south to the Mexican border. Bluebird populations declined because of habitat destruction, loss of nesting sites and the introduction of the European starling and the English house sparrow. Like all birds, bluebirds need water for bathing and drinking. A birdbath situated in the open to allow the birds to watch for enemies is ideal.
Bluebirds eat insects and fruit.
Don t use lawn chemicals if you want bluebirds. In the spring and summer, insects are their primary food. And insects are the only thing the young eat until they are almost ready to leave the nest. There are special feeders on the market designed for bluebirds that hold insects, such as mealworms, where the bluebird flies inside to feed. Bluebirds love berries which are critical to their survival in the winter when insects are unavailable.
