Squirrels playing dead?

Several videos of squirrels 'playing dead' have appeared on the internet in recent weeks. The first appears to be a single squirrel testing the tactic to assess its impact on humans:


The second, and perhaps more disturbing video involves two squirrels practicing some form of martial arts. One lays motionless for a couple seconds, while the other looks on baffled - acting as a human most likely would in such a situation. This mock battle is a clear indication that battle plans are being formed.


Although in the northern US, most squirrels will go into hibernation soon (if not already), southern squirrels are expected to continue their training throughout the winter. It is predicted that squirrel attacks will reach an all time high in the spring when the northern reinforcements come out of hibernation.
