 and loss of habitat. 



Lyle K. Sowls, Arizona Unit Leader, departed 

 for Southern Rhodesia early in Se])tenibei-, after 

 being granted a !)-nionth lecturesliip at the Uni- 

 versity College of Rhodesia and Nyasaland, a 

 branch of tlie University of London. Dr. Sowls 

 is assisting in the deve]oi)nient of a wildlife train- 

 ing curriculum for this institution, and expects 

 to do some researcli on tlie waithog during the 

 time he is in Africa. Appropriately, this research 

 will be on a species having some of the characteris- 

 tics of the peccary, Dr. Sowls" main research inter- 

 est in Arizona. 



Researchers serve a,s expert ivitnesses. — In June 

 1962, three employees of the Denver Wildlife Re- 

 search Center, Dr. R. B. Finley, J. R. Tigner, and 

 J. E. Peterson, were called as witnesses in a civil 

 trial at Greeley, Colo. The case was a damage suit 

 involving aerial spraying of endrinon a farm with 

 a subsequent kill of several species of warm-water 

 fish. 



In otlier instances where expert testimony was 

 required, Dr. J. "W. Aldricli, Statl' Specialist, iden- 

 tified scores of dressed carcasses and the cleaned 

 bones of confiscated ducks at Lafayette, La., re- 

 sulting in conviction of illegal duck hunters. Dr. 

 Aldricli is regularly called upon to identify birds 

 hit by flying aircraft, when such birds or feathers 

 are recovered. A recent and highly interesting

To obtain information required for waterfowl management, the Bureau, in cooperation with Canadian authori- 

 ties, conducts extensive banding operations of young, preflight birds on the far-northern nesting grounds. Band- 

 ing returns serve to identify breeding populations with flyway routes; provide means of determining longevity 

 and the effects of drought on flight routes: and make possible the identification of wintering grounds of given 

 populations. (Photo by Rex G. Schmidt)
