This state's classification carries no date range for the species.
IDFG's official 2026-27 Migratory Game Bird Seasons & Rules booklet gives woodcock no dedicated season/bag section (unlike ducks, geese, swans, dove, crow, and sandhill crane, each of which gets one) - woodcock is mentioned exactly once, generically, in a boilerplate definition of migratory bird types 'if there is an open season.' Idaho is at the marginal western edge of the species' range. Treated as structurally closed this cycle rather than not_present, since a season could in principle be authorized under the federal frameworks Idaho already uses for other migratory species.
No Idaho-specific population survey exists. Checked whether the federal USFWS Woodcock Population Status report (Singing-Ground Survey, SGS) gates this combo the way it does for eastern states: confirmed via USFWS's own SGS program description that the survey network covers only the eastern half of the U.S./Canada breeding range, consistent with IDFG's own note that Idaho sits at/beyond the western edge of woodcock range and has no dedicated season. No governing population/forecast source of any kind — state or federal — applies to Idaho woodcock.
