~ Banding 
Banding efforts during the summer were concentrated on Canada geese, In 
cooperation with G. Hortin Jensen, Flyway Biologist, U. S. Fish and Wildlife 
Service, Canada goose banding work was continued on Blackfoot and Island Park 
Reservoirs and initiated on North Lake Refuge in Jefferson County. With the 
assistance of F. Sheldon Dart and James S. Cromwell, U. S. Game Management 
Agent, goose banding on the Lower Snake River was begun this year, The banding 
on Dingle Swamp was done by Henry M. Reeves, Conservation Officer, and that on 
Gray's Lake by Elwood G. Bizeau, Biologist. 
The results of the summer banding are shown in Table IV.
