Anatomy: The American Robin is 9-10 inches (23-25.5 cm) long. Males and females are very similar in coloring; the male's head is darker and has brighter feathers. Young robins are paler than adults and have dark spots on the chest.

Diet: Robins eat small insects, spiders, and worms.

Nest and Eggs: Robins' nests are cups made from grass and mud. Nests are built in trees and shrubs. Females lay 3-7 light blue eggs in each clutch (a set of eggs laid at one time). The female incubates the eggs for 12-14 days.
