  • Bald Eagles can weigh up to 15lb., and are between 28-38 inches in size. Their wingspan can reach up to 7.5 feet. (For comparison: an osprey’s wingspan reaches up to 6 feet, and a red-tailed hawk’s up to 4.8 feet). This expansive wingspan is ideal for soaring, keeping Bald Eagles aloft for longer periods without flapping their wings.Their impressive wingspan is more than decorative: it allows them to fly at dizzying heights! Bald eagles soar 10,000 feet or more into the air, using thermal air currents to support their glide. This allows them to conserve energy for more important activities, like looking for prey and migrating long distances.We call a person an “eagle eye” if they have 20/20 vision, but Bald Eagles have much sharper eyesight than that! In fact, they typically have 20/40 or 20/50 vision, making them expert hunters. Not only can they spot a small animal two miles away with amazing clarity, but they have a 340-degree field of view—with even better peripheral vision than owls!

    Since Bald Eagles sport a white head of feathers, so where did the “bald” moniker come from? It turns out that it was a translation of the old English word “piebald,” meaning “white” or “white-headed.” And the Bald Eagle doesn’t acquire this crowning glory until they are 4 or 5 years old—with about four stages of feather shedding before that. Bald Eagles are said to have a grip 10 times stronger than a human’s. This comes in handy when they use their talons to pick up fish (their favorite meal) from a lake and keep hold of it while gliding through the air. It also allows them to snatch another bird’s prey from them midair (after hassling the bird to drop its meal—talk about cunning!).
