March is peak migration month. Imagine a day in the life of a migrating robin.

Observers in snow-covered, wintery areas are seeing robins eating berries. In places where rain and snowmelt softened the soil, people reported robins clustering at the bare spots, hunting for earthworms.

Norfolk, Nebraska: "There were 10 robins eating berries just before the snowstorm," reported Tim Eggers on February 24th.

Singing on Arrival
Observers are listening for the male's true song. The sound of continuous singing is the surest sign that robins are back on the breeding grounds.

Columbia, Missouri: "One student saw a robin in our large playground tree. Through the window, we heard one during an all-school assembly. We just listened to the robin calls and we say it was peek and tut," reported Ms. Elder on February 22nd.

A Day in the Life
In spring, robins feel restless, ready to migrate. Their whole body is urging them to establish a territory, mate and raise babies — but they can't start any of these until they arrive on their breeding grounds.
