We’ve chosen to acknowledge and shed light on Save The Eagles Day, which falls on January 10th, through a blog post celebrating these magnificent creatures. The day was initiated as part of efforts to rescue the bald eagle from the brink of extinction in the 20th century. Thanks to successful conservation efforts, this proud symbol of the United States, known for its power, courage, and freedom, was officially removed from the endangered and threatened wildlife list in 2007. While the survival of the bald eagle is no longer in jeopardy, the future of other eagle species remains less certain. Therefore, the relevance of Save The Eagles Day persists each year. To provide you with an insight into the captivating world of eagles, we’ve gathered 25 Fascinating Facts About Eagles That Could Alter Your Perspective.
