Robins nest

Some birds 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 blue prints in their brains, and instantly know how to build a perfect structure to hold the eggs they are about to lay. Robins nests are always alike, but have you ever seen a robin teaching another how to build a nest? A robin in North America goes through the set building process 2 or 3 times a year.
