Why does raw meat left out spoil relatively quickly, whereas hunters can kill the animal, transport a warm carcass a good ways, and render it in unrefrigerated conditions without it going bad?

I know nothing about hunting so I'd be interested to know!

EDIT: thank you so much to those who responded, especially the hunters! If I hadn't spent all my money on beer tonight I'd buy Reddit Gold for you all! (Ok not really but it's the thought that counts, eh?)

Food processing speeds up spoilage. When the animal is intact, the meat is relatively sterile. The skin prevents any bacteria from getting to the meet and the animals normal enteric flora is contained in the GI tract so the meet remains sterile until one of these barriers is broken. When the animal is butchered much more of the meat is exposed to the environment and often the meat is exposed to bacteria from the animals GI tract. Now that the meat has bacteria on it spoilage is inevitable refrigeration slows the process but eventually the bacteria will grow to a significant population and spoil the meat.
