See map 2, and reports at Smithsonian Institution with detailed 

 locations of eagle nests (active and inactive) for Chesapeake Bay 

 region (1970-1973), provided by Jackson Abbott. A total of 89 nest 

 sites (not all active in one year): 4 in Delaware, 45 in Maryland; and 

 41 in Virginia. The region is the most productive area for Southern 

 Bald Eagles north of Florida.
