Migratory Bird Populations Station 



A new unit of the Branch was established 

 through reorganization of the Patuxent Wild- 

 life Research Center, October 19, 196l, 

 This unit, the Migratory Bird Populations 

 Station, concentrates under the Station Di- 

 rector those phases of research dealing with 



national and international studies of migra- 

 tory bird population dynamics, including 

 bird banding and data processing. It serves 

 as a clearing house and a planning center 

 for developing various migratory bird sur- 

 veys and investigations involving coopera- 

 tion of operational personnel of the Bureau 

 and assistance from State, Canadian, and 

 other conservation agencies. Analyses of 

 data already available in the bird banding 

 files, in addition to information from cur- 

 rent surveys, are an important part of the 

 Station's initial work.
