Squirrels Use "Snake Perfume" To Fool Predators

Video stills show a ground squirrel chewing on a rattlesnake's shed skin and then licking its body to apply the masticated mush. The act most likely persuades serpents that another snake, not a squirrel, is in the area.

A new study suggests that this behavior is part of a host of tricks the squirrels have evolved to use to avoid predation.

California ground squirrels and rock squirrels chew on sloughed-off snake skin and smear it on their fur, according to a new study. The act most likely persuades the predators that another snake, not a squirrel, is in the area.

"To our knowledge this is the first case where [this idea] has been tested systematically and shown to have an anti-predator function—protecting the squirrel from rattlesnake predation," said study lead author Barbara Clucas.
