Buffalo in Yellowstone are not a useful reference point here. I hunt animals across the US, and I can assure you that flies and mud is the LEAST of the problems wild animals have to deal with. A particularly revolting example: https://cdnsciencepub.com/doi/10.1139/cjz-2018-0140#.W9tXqRNKgWo https://cdnsciencepub.com/doi/10.1139/cjz-2018-0140#.W9tXqRN... A study published in the Canadian Journal of Zoology in 2018 found that from 2014 to 2016, 70 percent of moose calves in west-central Maine and northern New Hampshire died of emaciation by winter tick infestation. On average, each animal hosted 47,371 ticks.
