Scrolling through youtube videos, it appears to me that there is an abundance of clips from Ngorongoro Crater and Masai Mara showing wildlife interactions, i.e. kills, fights, struggles over food, etc and not nearly as many from the Serengeti National Park. This was puzzling to me at first but I have thought of some reasons that this could be. Here they are:
1. More visitors in Mara and Ngorongoro-this combined with the smaller area they encompass means that wildlife interactions are much more likely to be recorded on camera than in SNP.
2. Greater density of mammals-Mara and the Crater also might be more concentrated in terms of animals, including predators, which means a better chance of witnessing interactions.
Does this all sound about right? Because there also appear to be a large number of such videos from small parks in southern Africa, none of which as famous Serengeti, that I can't explain.
