Waves in Minnesota
Large waves of robins appeared in Minnesota this week. When the weather is cold, robins can become gregarious again. They may revert to flocking to find food. They gather at night in communal roosts that can be noisy!
A young robin making its first spring migration north may end up hundreds of miles from where it hatched the summer before. It can easily get blown off course by winds or storms. All winter the young robin has followed groups of other robins, learning from them wherever they go. But once a robin has a successful nest, it often returns to the same place year after year.
