Frequently Asked QuestionsDo the young return with the adults in the spring of the next year?
Bald eagles start migrating at a young age, but the reasoning behind the migration is unknown. Some fledgling eagles migrate in a wide range for their first few years. Some return to their origin, some do not. No one knows if this is a conscious decision on the eaglets’ part, or if some just simply lose their way. How can I tell if an eagle is a male or female?
The most obvious difference between a male and female bald eagle is the bird’s size. Females tend to weigh more than males, have a larger wingspan, and have a body about a third of the size larger than a male bald eagle. When do bald eagles get their white head?
Bald eagles are not born with white heads. Their feathers are mottled light and dark brown and patches of white, and it is not until around age 4 or 5 that white feathers replace the brown on the head and the tail. This is a sign of sexual maturity. Where do bald eagles go in the winter?
Unlike other birds, bald eagles do not migrate for temperature reasons. For the most part, bald eagles can withstand cooler temperatures. However, when the lakes and rivers freeze over, the birds lose their main source of food, and so they begin to migrate to the coast or large rivers near dams, where the water remains open. Wind patterns play a large role in where bald eagles end up migrating. Bald eagles in Florida do not tend to migrate; they stay near their nests all year round. Northern bald eagles migrate south in the fall and return north in the winter.
