Another major detriment to bluebirds is the overwhelming competition from non-native starlings and house sparrows. Bluebirds are rural and do not nest in cities or towns, although occasionally they will nest on the edges of small towns. There are ways to increase bluebird numbers. One way is to provide nesting boxes, an effort underway nationwide. Kan-sans would benefit greatly from participating in this effort.
Bluebirds also exist in old orchards and cutover woodlands.
In these habitats they consume grasshoppers, flying insects, beetles, and caterpillars during short forays to the ground from an elevated perch during the summer. During winter they travel in flocks, feeding primarily on berries or fruits. The eastern bluebird's breeding season in Kansas extends from March through July, although the birds occasionally may initiate nesting into August. Peak breeding activity in Kansas begins in April. Normally, bluebirds raise two to three broods per year, often using the same nesting site each time.
