Some people think the US national bird is called the bald eagle because its white head resembles that of a bald person. Yet that same white head is fully feathered. The truth is more likely that the name “bald” is short for piebald. Piebald refers to being made up of different colors. With the bald eagle we have the white head and the blackish-brown body.
Fun Facts: The female bald eagle is slightly larger than the male. Wingspan ranges from 72 to 90 inches—that’s almost eight feet. Bald eagles have 7,000 feathers, weigh from 10 to 14 pounds and have a lifting power of about four pounds. They are the only bird that is unique to North America. They can achieve speeds up to 35 miles per hour.
