Remember the tourist in Yellowstone that "rescued" the baby bison calf because they thought it was cold? They loaded it into their mini van and drove it to Park HQ probably happy and proud of their rescue. The little calf was rejected by its mother when Rangers tried to reunite it with its mother. After several efforts to get the calf back with mama the calf was euthanized by park personnel.
I was a State Park Naturalist for the DNR for several years. Nearly every year some well meaning folks would drag a fawn deer to the park office. They would be hiking and see the fawn tucked away in the brush close to the trail and no mother around. Being completely ignorant they would scoop the fawn up and stress heII out of it by manhandling it the remainder of the hike and then hauling it in a car for several miles to the office. A simple phone call would have saved us all a lot of trouble and probably actually saved a deer or two. After I explained to them how a mother deer handled a young fawn it would fall on me to try to find the spot the deer was kidnapped from and replace it hoping momma would accept it. On at least one occasion I know the fawn died. I found it dead the next day when I hiked out to check on it. Most likely the stress of the event.
Critters have been surviving a long time on their own. And sometimes not, nature being what it is. Occasionally some human intervention is actually helpful or merciful. Many times it doesn't work out that way.
