Oregon manages dusky and sooty grouse jointly under a single "Blue Grouse" regulatory category (not split by species in the season table); same season/bag applies to both.
ODFW's Forest Grouse and Mountain Quail Parts Collection Summary ('wingbee' report, post-season hunter wing-collection) is the only quantitative instrument covering dusky grouse; a fresh, extensive search this pass (multiple query variations) confirmed the same finding as the Tier A pass -- no edition newer than 2021 (published 2022) is publicly located, despite the collection program itself continuing annually (wing-bee events held each March/April per ODFW's own current guidance). Active program, no dated fresher report -- treated as an open-ended wait, not a confirmed lapse.
