This unfortunate bull had stuck his head into a native's wire snare. He probably did this when he was smaller, because it appears to be snug around his neck and causing a visible ulceration. It's no wonder this fellow was irritable and chased all the impala away from where they were drinking. Natives set snares to catch small game, but it is illegal. Park personnel organize search parties to find and destroy them. [Masuma Dam, Hwange NP, Zimbabwe].
