Species Description
The American Robin is a common songbird of North America. Although its return is generally viewed as a herald of spring, robins rarely migrate more than a short distance. Save for some far northern populations, the American Robin tends to stay in its breeding range over the winter; however, it is one of the first birds within its range to lay its eggs in the spring. Earthworms and fruit make up the majority of the robin’s diet, with other insects and snails taken occasionally and small snakes even more rarely. It is primarily a ground forager, finding worms by staring at the ground to look for signs of digging. In the winter, fruit becomes a more important food; it is believed that robins vary their winter diet by selectively eating fruits that have bugs in them. When berries are taken exclusively (especially honeysuckle berries), the American Robin can become intoxicated, stumbling during its characteristic “running and stopping” behavior.
