Did you know that Eagles can see for distances of up to one and a half miles? Or that they can dive at 100 miles per hour? National Geographic Eagles 2017 celebrates this American icon by taking an intimate look at the bald eagle through a collection of breathtaking photographs. Easily recognized due to its white (Old English: bald) head, the Eagle is a symbol of strength and freedom. Each outstanding image is accompanied by insightful National Geographic information and a large grid with moon phases and international holidays. Sales of National Geographic calendars support vital exploration, conservation, research, and education programs. The calendar includes a 3-year at-a-glance page and is earth friendly, printed with soya-based inks on FSC certified paper.
