Their bills are brown. European starlings feed primarily on insects and small invertebrates. They also eat fruits, berries, some types of vegetables, seeds, etc. Often they can be seen foraging in grassy areas. They nest in cavities and are known to displace some native birds from their nest sites.
Females can have two broods per year.
During parts of the year starlings gather into huge flocks. In addition to their distinct whistles and their other sounds such as squeaks, rattles, and clicks, they are also adept at mimicking the calls of other birds and sounds in their environments. Starlings are highly adaptable birds which has made them a great success in surviving and thriving in our country. Like the House Sparrow and the Rock Dove who are also non-native birds, European Starlings are not federally protected in the United States. European Starling in breeding plumage.
