Massachusetts does not classify mourning dove as a huntable migratory game bird.Primary evidence: (1) MassWildlife's current 2026-27 migratory-game-bird regulations page lists the full species/date table (ducks, geese, brant, coot, woodcock, sora rail, Virginia rail, snipe) with no dove line item; (2) the codified regulatory definition of 'Migratory Game Birds' in 321 CMR 3.00 is limited to families Anatidae, Rallidae, and Scolopacidae — Columbidae (doves) is structurally excluded; (3) a full-text search of 321 CMR 3.00 found zero occurrences of the word 'dove.' Secondary sourcing (dovehunting.org, unverified independently) attributes this to an 1903 state-law classification of mourning dove as a protected songbird rather than a game bird, a status that per that source has never been legislatively reversed. Do not treat as 'no_season_found' — this is a structural non-game classification, not a data gap.
Confirmed absence — structural: Massachusetts does not classify mourning dove as a huntable migratory game bird at all (Columbidae structurally excluded from 321 CMR 3.00's "Migratory Game Birds" definition, matching this record's own classification), so there is nothing for a population forecast to gate.
