I caught a rabbit in a live wooden trap I made when I was a teenager. I let him go and didn;t eat him but I've eaten at least 2 since (in the last 30 years), yeah probably more than 2. I shot those though. I've set some snares while out practicing survival techniques with my daughter, but we've not caught anything yet. I suppose we could if we set more than one....probably 5 or so, and if we paid more attention.
I trapped some quail when I was a kid with a trap my friend made. I didn;t really trap them, I just tagged along. We let them go also. I was about 13 I guess, and my buddy had this hole in the ground/funnel/coffee can trick. I could do it again if I had to, I think....hmmmm, maybe.
I've eaten fresh crawdads cooked right by the creek where they were caught. Ft. Hood, Texas when I was about 15 or so. Since then, I've eaten them again at least once....again, cooked within about an hour of catching them.
I ate a few baked ants on a dare about 4 years ago. We were sitting around building the campfire before dusk on a camping trip. One of us started talking about these ants that were traipsing through our site (or us through theirs). That started a discussion about survival and what people would eat and it turned into a dare. I cooked about a dozen...most fell into the fire or someway or another got away. Some I had to smash a little to get them to stay put on the stick while they cooked (I sure would hate for somebody to do that to me). Anyway, I ate probably 3 or 4, then two other guys ate some. We ate them whole....head and all. I really don;t think they needed to be cooked, exactly, but that's just what people think of when eating wild stuff...so we did it. I can;t remember there being any particular taste...if somebody asked I'd probably say they tasted like..........yep, chicken. But I doubt that's true...there really wasn;t a taste... maybe a little acid or something, but I can;t be sure now.
Most of the other stuff I've eaten I've either killed with a rifle or shotgun or somebody else did. Cougar, deer, oryx, rabbit, quail, dove, pheasant, wild pig, quail eggs, rattlesnake (then neatsfoot oil/tanned the skin), duck (domestic - my daughter's), softshell turtle, nearly every species of fish that can be caught in Texas, New Mexico, or So. California. Ate quite a bit of a blue shark I caught 12 miles off-shore from San Diego. Mackeral from Santa Barbara....cooked them in a foil/charcoal makeup in the window of a motel there. While deer isn;t bad, the best I've tasted was the cougar and the oryx..... both a real treat.
The rattlesnake was unique. Killed with rocks, a stick, and finally, MY knife. Another camping trip in the desert outside El Paso. Skinned him, cleaned him, and cooked him right there that evening. Slices of him we put on rocks ringing the fire and other parts we held near the fire with sticks and, again, MY knife

Now if anything was like the old saying "Tastes like chicken" I suppose that was it. We had no salt but somebody had Lays potato chips and I rubbed some all over a few slices of mine, and ate a mouthful of them during another bite or two. If I remember right, it was pretty good.... maybe it was the fun of camping or the camraderie, but I remember it tasting pretty good.
When I was 18, I ate a goose I raised since I was 16. I had come home one weekend and my Dad was tired of taking care of him. My mother was raised on a farm in Ohio so she knew what we had to do, so she coached us through butchering it and then she cooked it.
That's about it. Nothing too awful exotic I suppose. If I were trapped in the wilderness, be it forrest, desert, mountains, plains, whatever, I know that IF I did snag something, I wouldn;t have a problem eating it.
I saw Les Stroud (Survivorman) trap and cook a desert rat in his Utah mountain bike episode. He didn't clean it or anything, just took the whole thing and hung it over the fire. He cooked it for a long time, fur, tail, guts and all. Then he cut into it for supper. My wife and daughter were a little aghast. I didn;t say anything but Iknew I could do it without too much problem. It's catching it that would be hard for me.
I guess that's about all I've eaten.
EDIT: Snails! Aha! I knew I forgot something (probably remember another thing or two). I ate some snails at a restaurant in El Paso many years ago. They were gritty but EXCELLENT. We had these little forks and some butter mixture to dip into.
Well, that isn;t why I remembered and came back to edit. I ate some California snails we caught, took with us, and cooked right by the lake. Now THEY didn;t taste all that good. Might have been the way we cooked them I don't know, but they didn;t settle quite well. My buddy boiled some and this stuff was floating around in the water like egg-drop soup or something. We fried them after that in bacon grease, but after seeing them in the water they just didn;t look appetizing any more.
