Focus on Feathers

Each year, during their molting time, eagles lose some old feathers and grow new ones. Not all feathers are lost at once. It takes several months. Young eagles go through four different plumages until they reach their mature adult plumage, which would be the fifth plumage type. These are: Juvenile, White-belly I, White-belly II, and Adult transition plumages. Once they reach maturity, it is likely that bald eagles molt their flight feathers just about every year.

What plumage would you call this bald eagle?
