Personally, I'm not a bird hunter, but I did have a home I rented out for about 2 months a year to bird hunters, for 10 years. One group drove almost a thousand miles, just to hunt cranes, because Nebraska didn't, at that time, allow crane hunting. One of the guys had one mounted to stand up in a corner of the living room. And, I've been told...
While it is possible; when it comes to spot and stalk, you better be part Indian. They stand really tall, and they see really well!
Decoys are available, and they aren't real tough to decoy. IF you live in the flyway. Around here the flyway changes constantly dependent upon how much pressure they receive. It's 60 miles or more in the last ten years.
As far as eating them... marinated and deep fried chunks, they taste about like venison. Don't overcook them or they get real chewy. Also had them marinated in red wine and prepared in the crockpot in a nice gravy. They got so tender that they cut easily with a fork in that method.
Pretty tasty either way.
Was told once to cut a few slits, insert bacon and/or onion, and bake them. And, it wasn't to bad tasting that way, for about the first 10 minutes you chewed each bite!! But, after that your taste buds just sorta wore out, like chewing a stick of chewing gum too long. Never did get it chewed up, you just cut really small bites so you could swallow it easy, after you got tired of exercising your jaw muscles.
