Miner, Jack (1865-1944), was a Canadian bird conservationist and researcher of North American bird migrations. He established a bird sanctuary on his farm near Kingsville, Ont., in 1904. Miner studied the migrations of ducks and geese by marking thousands of these birds with numbered metal leg bands, then releasing them. Hunters returned the bands from birds they shot. In this way, Miner learned where the migrating birds went. Friends established the Jack Miner Migratory Bird Foundation in 1931 to help him continue his research. Miner was born John Thomas Miner in Dover Center, Ohio.
