Duck Banding

A close-up of duck banding at Johnson Lake, Saskatchewan, Canada in the early 1950’s; U.S. game management agent Bernhardt Dahlan attaches a leg band that may one day be recovered by researchers or a member of the public, adding to the U.S. Fish and Wildlife Service’s storehouse of information about duck breeding and migration. This data, in turn, influences the setting of annual migratory bird hunting regulations, and can lead to changes in the ways National Wildlife Refuges are managed for maximum biological productivity and optimum public use for priority recreational activities like fall hunting and birdwatching.
