If I wanted ALL THREE, in prime breeding plumage, in one trip I'd be looking at the Southern and the Central Valley of California the last two weeks of the season.....and I'd be looking at a Guide to be sure I wasn't hunting heavily gunned public marshes where I might not be able to get a permit.....
Texas has Cinammons but for the most part the Cinnamons arrive after the season.....I gunned Texas for MANY YEARS and never saw one only to hear...."boy if es could just shoot em now" two weeks later....
Great Salt Lake for A WORLD of Shovelors..and people that don't despise them as "trash".....
South Florida for prime Bluewings AND Fulvous and Black Bellied Whistling Ducks.....
Let me know if you need Guide recommendations for those places...all a little tough to free lance on a single trip due to equipment or access.....
