My Fascination with Bald Eagles.
It may be hard for some folks to understand why I have this fascination with Bald Eagles. It started in my youth. I never saw one until 1976. It wasn’t until my first trip to the Grand Tetons that I saw our Nation’s symbol. It is why I read and thing everyone should read “Silent Spring” by Rachel Carson. One of the first studies of the numbers of Bald Eagles showed that there were only 487 nesting pairs in the lower 48 States in 1963! Because of the widespread use of herbicides and pesticides, primarily DDT, Eagles and other Birds of Prey, were almost eliminated. Rachel’s book helped to bring attention to how DDT effected the birds. It was prohibited to use and as of 2006 our nesting population was up to 9789 pairs. We have a long way to go to reach the numbers of the 1700s and 1800s. I am fascinated with them because I never thought or dreamed they would survive. I find them so majestic in flight. I only hope that people who are growing up seeing so many never take them for granted and will always appreciate their comeback.
