First Robin |

Waves of Robins We define a wave as three or more robins. In southern areas, waves of overwintering robins are commonly seen in large flocks during the winter. In northern areas, waves of robins are a sign of peak migration. The first robins of spring are usually seen alone; waves of robins arrive later. |

Nesting Behaviors Watch for signs such as the male or female flying with nest materials, or the female with mud on breast. Both gather nest materials but usually only the female builds. She may begin within a day or two after arrival. Nests usually take 2-6 days to build. |
||
Migrating Earthworms Even though they only travel a few feet, earthworms undergo a "vertical" migration each spring after the ground thaws. The appearance of the first earthworms is a welcome sign of spring, and is often closely tied to the arrival of the first robins. |
