"_ In culinary terms, venison can be meat from deer, elk, moose, caribou, antelope and pronghorn._"
We refer to most antelope wild meat as venison, sometimes label will specify which animal. Ironically our biltong (spiced dried meat) nearly always lets you know, since beef biltong is a lot cheaper than say Kudu or Ostrich biltong.
Wild birds in the Ostrich are farmed and we get the meat which is super lean and healthy to eat.
Wild pig (Warthog) cooked on a spit braai or potjie is delicious as well, many unusual things may be found in restaurants like cane rat or crocodile depending on the region and restaurant.
Ooooh, I've never had ostrich either. I didn't realize that they were a game animal in some places. Here they are so exotic that I don't think most people would even consider eating them. I no longer eat meat of any kind, so I will likely never try it myself...but I'm a bit saddened that I didn't have the opportunity to try while I was still an omnivore.
