Road to Preservation

Why are mule deer being blindfolded, sent up in helicopters, and having their teeth pulled? It’s all to track and conserve their migration routes.

"As a small group of scientists and volunteers waits by the side of a gravel road here, a helicopter swoops down, carrying two blindfolded mule deer in slings. It hovers for a moment in a furious swirl of rotor-blown snow, detaching the deer slings. As it lifts and turns, the team runs into the stinging cloud. Team members carry the deer on canvas stretchers to a spot to be weighed and tested. From each animal, they draw blood, pull a whisker, check a GPS collar or put on a new one, take a rectal temperature and fecal sample, perform an ultrasound on the haunches, shoot a local anesthetic into the jaw, and pull a tooth. Ten minutes of probing and testing later, the deer are freed and dash off, with numb mouths and doses of antibiotics, perhaps wondering what in the world just happened."
