Ostrich: yes plenty of times, and ostrich eggs, too. These are reared in South West France, and also in the US, for food and for the leather.
Bison: yes, again plenty of times, but never found the eggs for sale...
Crocodile: no, never had any of that, though I had alligator when I was in Florida, in the Everglades.
Boar: again quite a few times when I lived in Paris; my butcher used to get a whole boar delivered on a pallet and cut it up in his shop. The meat counter at my supermarket has some "boar" at the moment, but imported from the US... I declined.
Horse: again this was while living in Paris. SWMBO was not happy when I told her what it was.
Deer: I don't know what kind, but I've had venison no end of times in the UK, France and the US.
Now for a few things not on your original list...
Donkey: I used to be able to find some chorizo imported from Spain that listed in its ingredients "meat of donkey, horse and pig".
Goat: I've had this a few times in Mexican restaurants in the US, and a couple of times in Indian or Pakistani restaurants.
Duck, Goose, Guinea Fowl, Pheasant, Grouse, Partridge, Quail: the first three are almost as common as chicken over here, quails are common and easy to get, but I don't eat them as often. Also, I've eaten the eggs of duck, goose and quail. I forget which, but either duck or goose eggs are not for sale in France; my egg and cheese merchant once explained to me that one of those has much thinner shells, and so there is a greater risk of contamination through the shell. In the UK we used to get both.
Rabbit and hare: I cooked a couple of hares in November; they were delicious. In the US I used to be able to buy rabbits from time to time at the supermarket, but there seemed to be no logic or timetable to their availability. In the UK I used to buy rabbits for £1 each from the Granger Market in Newcastle.
Pigeon and squab: I've had these a few times, in France and in the US.
Snails: both land snails and water snails (whelks and winkles). And limpets... not exactly snails, but similar and wild. I've eaten them raw, pulled straight off the rock.
Oysters: literally hundres of times... And while we're on the subject of seafood: razor clams, cockles, mussels, scallops, abalone, conch, lobsters, crabs of at least half a dozen varieties,
warty venus,
dog cockle,
lambi (on Martinique)... I'll not bother to list all the different sea, river and lake fish that I've bought from the fishmonger or eaten in a restaurant, I'll just mention the pike and perch that I caught in a friend's pond and the sturgeon that I ate in Moscow (a friend's dad brought it from his fishing trip the North).
Insects: chocolate covered ants (do these count, if the insects are less than 1% by weight of the finished food?), locusts and grasshoppers, silkworm pupae (
번데기, I could get them in cans in my local Korean supermarket).
Dog, cat and rat: pretty sure I've had these passed off as other meats in dodgy hole-in-the-wall restaurants or from street vendors.
Jellyfish: sold in strips, dried and salted, in the Korean supermarket; use it like noodles.
Sea urchin: I've eaten this a few times in France, and used to buy urchin tarama before the supermarket stopped stocking it (I think that not enough people bought it).
Bullfrogs' legs: my son ordered these in a restaurant in New Orleans, and let me try one. I've not yet tried ordinary frogs' legs here in France (though they are mostly imported from Indonesia, and have been for a long time).
There are almost no animals or parts thereof that I would not try, with the exception of endangered species. I would not go searching out a Nigerian restaurant in London to get gorilla's palms.
Then we could get on to less common parts of common animals, like pickled lamb's brain, duck gizzard or
sweetbread (calf's thymus).
Tried a back leg but found it a bit "Greasy" so left the rest!!!!
