16. Abstract (Limit: 200 words) 



Colonies of pelicans, cormorants, gulls, terns and black skimmers were inventoried 

 in 1976 from North Carolina to Key West, Florida. Five teams of investigators used 

 ground and aerial counts of nests or adults, or both, throughout the spring and summer. 

 This atlas shows the location of each known active colony and includes information on 

 nesting site and substrate, species composition and numbers, nesting stage, and 

 inventory method. Field work was conducted in conjunction with a survey of wading 

 birds under the direction of T. Custer and R. Osborn at the Patuxent Wildlife Research 

 Center.
