Feeding Bluebirds are ground feeders. They prefer to feed upon insects whenever available. Bluebirds perch above ground level to hunt for insects. When insects are not available, such as in the winter, they will feast upon fruit. Bluebirds have been known to eat from feeders that offer mealworms and raisins.
Bluebirds also participate in courtship feeding during breeding season.
The eastern bluebird is found east of the Rockies, including into Canada and Mexico. Bluebirds require semi-open land with short grasses and gardens that are surrounded by woodlands. Bluebirds have a territory range that is anywhere between two to twenty-five acres. Bluebird pairs will not usually nest within three hundred feet of another bluebird pair. In the spring they return to their previous breeding territories.
