In the Southeast, on the lands of the Cherokee, Chickasaw, and Choctaw, Purple Martins nested in dried gourds hung up by Native Americans. This relationship might have developed because Purple Martins defend their turf, says Kelly Applegate, a tribal member and Commissioner of Natural Resources for the Mille Lacs band of Ojibwe. White settlers copied the practice and put up gourds and birdhouses, too. But they also cleared forests where martins once nested and introduced House Sparrows and starlings that drove them out of woodpecker holes. Purple Martins now depend almost entirely on artificial nest boxes to survive. Kelly is encouraging people to provide homes for martins.
