Regular-season limits from each state’s official 2026-27 regulations. Possession limits count birds at home too. Federal rules apply on top of state rules, and some WMAs and refuges set stricter limits. Louisiana has its own limits, including a closed first 15 days for mottled ducks: see the Louisiana rules.
