Those facial birth defects began occurring at the same time on newborns of both deer species in Montana, as well as elk, bighorn sheep, bison, moose, pronghorn antelope, mountain goat, domestic calves, domestic goat kids, domestic sheep, llama, other mammals including domestic dogs, on individuals of multiple bird species and on newborn human children. Most of those never get near cheatgrass, but the parents/mothers of all were exposed to something at the same time during 1994 and every year since that is causing them to have young with facial malformations. Imidacloprid began being used in states upwind of Montana and in Montana in 1994. Now it is used all over the U.S. and Canada in huge quantities, being the most used insecticide in the world. Some animals, especially grazing animals, in other countries now have underbite or overbite, but prevalence there is unknown. Also, check out the study I referenced above. If anyone on this website loves mule deer, you should pay attention to what is happening. All you have to do to see lots of photos of the underbite on any of those mentioned species is type the species name, then underbite images on Google. By the way, for some reason, there is a much higher prevalence of overbite on white-tailed deer in eastern U.S. than here in western U.S. In eastern states the deer hunters call the deer with severe overbite "Dork Deer." You can see their photos by typing Dork Deer images on Google. In my humble opinion, the deer are not the dorks. I do not like animals with birth defects to be made fun of.
