WA state is the best waterfowl hunting state in the country and it isn't even close. 107 day season, 7 bird limit...including 7 greenheads....huge species variety.
Field hunting for wigeon/mallards/pintail on the West side will blow your mind...legitimate duck tornadoes are guaranteed when you're on the X. Tons of lesser and snows as well.
The tidal estuaries have resident and wintering birds all year long, and when the sheet water floods inland...the brackish tidal marshes are insane. I had soooo many Dec/Jan hunts there during a hard freeze when I'd have my 7 birds in the first 15-30 minutes.
Then you have the entire Columbia River basin...high desert greenheads and Greater Canada's that will make you think "North Dakota who?!"
Big river diver hunting for redheads, cans, bluebills....we're talking Great Lakes quality stuff here...
Of the few things I miss in WA, the waterfowling is definitely one of them.
