Posted by , Updated on December 7, 2016

January 10th is the Save The Eagles Day, and we decided to raise awareness of this day and eagles in general by writing a post dedicated to these magnificent birds. The Save The Eagles Day was started as one of the campaigns to save the bald eagle, who was facing extinction in the 20th century and the efforts were successful as it was removed from the list of endangered and threatened wildlife in 2007. The national animal of the USA and a symbol of power, courage, and freedom, the bald eagle has been saved, but the future of some other species is still uncertain, making Save The Eagles Day topical every year. To show you how amazing creatures eagles actually are, we compiled this post with 25 Interesting Facts About Eagles That Might Change The Way You See Them.
