A robin in North America goes through the nest-building process two or three times a year. They are expert builders! Some robins can live up to 12 years, according to banding studies. These birds may have built 20 or even 30 nests over their lifetimes!

Robins don't need written instructions for building their summer homes. They follow the "nest-building blueprints" in their brains, and instinctively know how to build the perfect structure to hold the eggs they're about to lay. Robins' nests are always alike, but have you ever seen a robin teaching another how to build a nest?
