Can you tell the age of an eagle by the size of its beak?

While it is not possible to accurately determine the age of an eagle by the size of its beak, there are some general characteristics that can help determine the age of an eagle. The beak of an eagle is made of keratin, the same material as human hair and nails, and grows continuously throughout an eagle's life.

Young eagles have a smaller and smoother beak than older eagles. As eagles age, their beaks become longer, thicker, and more curved. Additionally, the tip of the beak becomes more pointed with age. However, other factors such as diet, environment, and genetics can affect the size and shape of an eagle's beak.

Therefore, while the size and shape of an eagle's beak can provide some general information about the age of the eagle, it is not a reliable method for determining the exact age of the bird.
