Nestlings are fed soft-bodied invertebrates immediately upon hatching, but as they grow older, they are fed a larger variety of foods. Both adults remove fecal sacs from the nest at first, but this behavior eventually ceases, and the nest quickly becomes soiled. Males mated to more than one female give little or no parental care to the brood that hatches last. The nestlings leave the nest when they are 21 to 23 days old, but they continue to be fed by their parents for a few days. After reaching independence, the fledglings form flocks with other juveniles.
Pairs reuse nest sites within the same season, as well as in subsequent seasons.
If the first clutch is successful, most pairs do not raise another brood. If the first clutch fails because of predation or weather, the pair will attempt a replacement clutch. Double broods are more common in the southern portion of the starlings' range. In winter, starlings in the midwestern United States migrate, but starlings in the East tend to be residential. Young birds migrate farther than older birds.
