This state's classification carries no date range for the species.
Confirmed absent from the official 2026-27 season PDF, MDIFW's dedicated migratory game birds page, and the season-dates-bag-limits landing page. Species occurs in Maine biologically but the state has not opted to open a hunting season for it, unlike many other states in this product's scope.
Confirmed absence — structural: Maine has no mourning dove hunting season at all (confirmed against the official 2026-27 season table, matching this record's own classification), so there is nothing for a population forecast to gate.
