Sitting on fences, low tree branches, or perched upon their artificial nest boxes, you will find this small bird with round head and big belly.
The males will have blue above and a rusty colored throat and chest, while the females will have grayish with bluish wings above and an orange brown breast below.
They often nest in nest boxes due to lack of habitat but will nest in small holes of trees. Males offer nesting material and food during courtship. Females build the nest and may have more than one successful brood per season.
They generally do not visit birdfeeders but can be tempted in by offering mealworm feeders. Bluebirds will migrate, however in certain parts of the United States, they will remain in their breeding territory all year.
