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.
Great Blue Heron
The great blue heron is the largest heron in North America, standing up to 1.4 meters tall. These patient hunters can stand motionless for extended periods before striking at prey with remarkable speed. They nest in large colonies called heronries, often returning to the same site year after year.
