Seriously...first thought was food (we carry deer like that). However typically you don't keep the front end, all the good meat is down the back.
Second though is maybe its used for some sort of periscope camo? It looks like somewhere in North Africa, where there isn't much cover where peeking over a ridge is likely to get you spotted. If it was a true dead animal the head would not be up like that.
You guys have to admit, if its a hidden spotting scope it's a damned ingenious idea
