Bald Eagle Population Size

 

Since the bald eagle was fully listed under the Endangered Species Act, the number of nesting bald eagle pairs and productivity (number of young fledged per nest) have been monitored throughout the lower 48 states. This effort has produced an excellent data set which was used to develop the population table, map and chart in the links below.  Follow these links to see how bald eagle numbers have responded since DDT was banned and the Endangered Species Act was passed.
