It appears that the friendly group of men in this video are helping out a distressed moose calf, but what they’re really doing is risking their lives.
Moose are enormous, extremely powerful animals. And unlike deer, when they are threatened or protecting a calf, they can be absolutely deadly. These bikers mean well, but got very lucky. Assuming that the calf was abandoned could have been a deadly mistake.
It is always a good idea to observe an unattended baby for a good chunk of time to make sure that the mother is not nearby. If the animal has truly been abandoned, call appropriate animal services for your area. Processed goods like Gatorade could prove harmful to the wild animal.
