Males' wing and tail feathers are blue with black or gray shafts and tips. Their heads are a lighter shade of blue, which fades into a red throat and breast area. The abdomen is white with light blue tips on some of the longer feathers. Females also exhibit this pattern of coloration, although they tend to be duller than males and posses more gray color in their plumage. The Eastern bluebird has a variety of feeding habits.
Food choices tend to be seasonal.
In summer months, these birds feed mostly on beetles, crickets, caterpillars, grasshoppers, and other insects. Reproduction Mating occurs in the spring and summer months. Some studies have shown that more than one female or male have been involved in some broods, suggesting that monogamy is not always the rule within this species. A mature female will typically raise two broods each season. Construction of the nest is done primarily by the female and takes approximately 10 days to complete.
