About These Birds
American Robin
The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.
Common Starling
The common starling is famous for its murmurations — vast swirling flocks of thousands that create mesmerizing patterns in winter skies. An accomplished mimic, it can imitate other birds, car alarms, and phone ringtones. Introduced to North America by a group intent on establishing every bird mentioned by Shakespeare.
