Do robins fly south to winter?

Answer 1

It all depends where you are. Part of the population is migratory. Robin's breeding range goes all the way up to Alaska, but they sure don't winter there and they winter in areas where they don't breed. However robins are found year round in many parts of the states, depending on food availability & temperature. Now if the robins are the same year round is a different question, it's possible tha they are going south and being replaced by the one's in the north. Some will stay a bit more north than indicated and numbers of migrating birds may depend on the year. Here's a distribution map showing the winter/breeding/year-round areas
