Denver WUdUfe Research Center. — Plans for 

 construction of new facilities progressed satisfac- 

 torily at the Denver Center during 1964. A con- 

 tract was executed for an extension to the pesti- 

 cide-waterfowl utility building. Outdoor pens for 

 research on eagles were under construction, and 

 plans for the addition to the Forest Animal Dam- 

 age Laboratory were in the final stages before 

 requesting bids. Numerous items of needed lab- 

 oratory equipment were !u?quired during the year. 



Of primary interest was completion of plans 

 and solicitation of bids for a Chemical-Wildlife 

 Evaluation Laboratorj' authorized in 1964. The 

 1-story structure will be 164 by 215 feet and will 

 provide 50 or tnore offices, laboratories, animal 

 rooms, and other space for this important Bureau 

 program. Construction is expected to begin in 

 the spring of 1965. 



Migratory Bird Populations Station. — In Octo- 

 ber 1964 the bird banding records center and the 

 machine data processing unit of the Migratory 

 Bird Populations Station were moved to new 

 quarters that provide 10,000 square feet of air- 

 conditioned floorspace, with humidity control in 

 the part housing the nuichine data prcK-essing unit. 

 Proper juxtaposition of the two units permits a 

 more orderly flow of data through the station, a 

 matter of great as.sistancp in coping with the in- 

 creased workload. 



Northern, Prairie WiMIlfe Research Center — 

 Construction of pliysical facilities at the newly 

 established Xorthern Prairie "Wildlife Research 

 Center continued during 1964. The fiekl labora- 

 tory, equipment building, and residence at the 

 Woodworth Station of tlie Center were completed 

 in February 1964. A (M>ntract was awarded in 

 May 1964 for constiniction of the main administra- 

 tion-laboratory building at tlie Jamestown head- 

 quarters, and tlie basic building was well on the 

 way to completion by year's end. Plans for the 

 next construction stage, to l>e started early in 1965, 

 and to include a garagi, equipment building, one 

 residence, and outdoor facilities for experimental 

 work, were being developed by staff engineers of 

 Region 3. 



Patuxent Wildlife Research Center — Construc- 

 tion of an animal laboratory building at the Patux- 

 ent Center was completed in August 1964. Tliis 

 structure, built by the National Institutes of 

 Health, will house experimental animals used by 

 NIII reseaiTh personnel in conducting studies on 

 the causes of progressively degenerative disorders 

 of the central nervous system in lower animals and 

 man. The research to be accomplished is part of 

 a program, established in 1962, in which the Na- 

 tional Institute of Neurological Disease and 

 Blindness, NIII, and the Patuxent Center 

 collaborate.
