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.

The Chesapeake Bay watershed is a prime feeding ground in both summer and winter, drawing the eagles from as far north as Canada and as far south as Florida. Watts said their breeding space is now at a premium, so their population growth should begin slowing. An increasing number of injuries and deaths related to intra-species combat is one telltale sign of how crowded they've become.
