Abstract: This is the report from the 1974 aerial trumpeter swan survey. The tri-state trumpeter swan survey is an annual survey, conducted during the first or second week of September by the US Fish and Wildlife Service and cooperating state and federal agencies. The purpose of the tri-state survey is to determine population levels and cygnet production of the tri-state trumpeter swan sub-populations in the fall, before wintering swans arrive from the northern latitudes. The area surveyed for trumpeter swans is commonly referred to as the tri-state area, which includes southeastern Idaho, northwestern Wyoming, and southwestern Montana.
