Centuries prior to the colonization of the Americas, Purple Martins began to nest in gourds that people hung to store food and water and became companion species for many tribes. The birds that European settlers brought with them drove Purple Martins out of their wild habitats so that now they can only nest in birdhouses that people build to prevent their extinction. Without dialogue or narration, Homing follows the migration of Purple Martins from the Amazon to the Great Lakes, between the conservationists who study them and to the houses they are dependent on for survival. —Tamer Hassan
