The bald eagle is more than the symbol of the United States—this feathered, fearsome flier is interesting enough to have an entire day dedicated to it. While Save the Eagles Day originated as a way to raise awareness about the then-endangered species, it now serves as a time to learn about the now-thriving animals. Save the Eagles Day is observed annually on the 10th of January.
Some species of eagles are on the endangered list. However, due to the work of scientists and the public, the Bald Eagle was removed from this list in June 2007. There are more than 70 species of eagles throughout the world. The only exception is Hawaii, where no species of eagles reside. Poaching, pesticides and other dangers continue to threaten eagle populations.
Here are five facts you may not know about eagles:
- Females are slightly bigger than their male counterparts. The fellas weigh between 7 and 10 pounds, and females can weigh up to 14 pounds.
- Eagle-eyed, indeed: Eagles can see as much as eight times farther than humans—and their eyes are equipped with infection-fighting tears.
- While the bald eagle population has steadily increased after a severe drop in the mid-20th century, most of the population’s fatalities remain human-related. Trauma caused by impact with manmade structures, gunshot and poisoning are the leading causes of death.
- Eagles sound sort of goofy. In most TV shows and movies, their calls are replaced with those of hawks, which have a more fear-inducing cry. (Here’s how eagles really sound.)
- If they’re hunting, eagles can dive up to 100 mph. But when they’re flying casually, they go about 30 mph.
