Virginia's bald eagles thriving at a never before seen level after pesticides ban.

A total of 1,070 occupied bald eagle nests were counted in this year's survey by the Center for Conservation Biology at the College of William and Mary. It's the first time more than 1,000 have been counted since the survey started 60 years ago.

Mitchell Byrd is retired professor who has been doing the Virginia survey for 40 years. When he started, he wouldn't see a single nest along the James River. He's heartened to see so many bald eagles now. "It's indicative of what we as a species can do," Byrd said, "if we set our minds to it."
