Monique does not hesitate to paint predation scenes. The wolf keeps ungulate populations healthy by killing individuals that are sick, wounded or infected by parasites. In fact, overcrowding is the main factor causing diseases and increased parasites in a species. First and foremost predation by the wolf helps to prevent overpopulation among large herbivores. Being an opportunistic hunter, the wolf also captures healthy subjects, most often young individuals offering the least resistance. In doing so, it regulates moose, elk, bison and beaver populations, etc. Wolf specialists agree to say that only one hunt in ten ends with the capture of a prey. Some adult moose face up to the pack, which is sometimes forced to give up the hunt. Other ungulates find refuge in water, an instinctive trick giving them a clear advantage over their pursuers.
