Miner was one of the first conservationists to determine the migratory paths of birds. In August 1909, he constructed a successful duck trap. His subject was
banding with his own hand-stamped aluminum band. Along with address information, his bird tags quoted
scripture: "Keep yourselves in the love of God—Jude 1-21" and "With God all things are possible—Mark 10-27". Late that year, his original band was recovered in
Anderson, South Carolina. This marked the first complete record for banding migratory birds. In the spring of 1915, Jack Miner successfully adapted his trap to capture Canada geese. He conceived a trap with two separate ponds, adjoined by a canal. The canal was covered with network and fitted to trap doors at either terminus. At the time, it was not known where geese made their summer roost. Only a general northward direction was known from settler reports in Northern Ontario. Miner's captured goose was fitted with a tag giving the postal address of the conservationist. Subsequently, in October of the same year, Jack Miner received a letter from the
Hudson's Bay Company in
Moose Factory, complete with his tag. The letter indicated that the goose had been killed by a Native American in the Hudson Bay District. This initial success and increasing interest nationwide spurred on an expansion of the tagging operation. In 1916, hundreds of geese were tagged, along with various other waterfowl. By the fall, tags were coming in from all along the eastern shore of
James Bay,
Hudson Bay, and as far abroad as
Baffin Island. A second route south into the
United States followed the Mississippi Flyaway, into states such as North and
South Carolina,
Georgia,
Alabama and the gulf coasts of
Florida. Often, these tags were returned by poachers, curious
Native Americans or the
Royal Canadian Mounted Police. Using information garnered from these returned bands, the migratory habits of Canada geese were mapped. Miner's religious inscriptions garnered the interests of active missionaries. This provided an avenue for their return outside of game hunters in the Hudson Bay region. On one occasion, Reverend W. G. Walton, an Anglican missionary, hand delivered a pocketful of tags from Hudson's Bay. He had received these tags from as far as Baffin Island from natives. Thousands of subsequent bird taggings over the following years produced copious data that would help to establish the U.S.
Migratory Bird Treaty Act of 1918, representing an agreement between six nations making it unlawful to capture, sell, or kill certain migratory birds. In 1923, Miner published an account of his
banding methods and waterfowl conservation studies in
Jack Miner and the Birds. It was very popular: all 4000 copies of the first print-run sold out in nine months. The book is still in print. ==Public outreach==
