SPECIAL SCIENTIFIC REPORT — WILDLIFE 
This publication series (established in 1949) of the Fish and Wildlife Service contains reports of investigations related 
to wildlife. Each is published as a separate paper, but for economy several may be issued in a single cover. The Service 
distributes a limited number of these reports for the use of Federal and State agencies and cooperators. A list of recent 
issues appears on inside back cover.
