Inside a Robin's Nest Did you notice the cup-shaped nest? The robin made it from twigs, grass, and mud. Why do you think she used these to build a nest? The mother robin is snuggled in the nest. Did you guess that she was sitting on some eggs? She made the nest 10 feet up in the tree. Why do you think she put it there? (Hint: Foxes, owls, and cats prey on baby robins.) How else can the tree protect the nest? Back
