Bear startled by reflection - GIF

[Frank S]

I tried it with the porcupine that comes to my door every night. He was NOT impressed.

Did the porcupine return the following night? Many times when they have been frightened, they move one never to return. Since they are a docile creature and do not possess any means of fighting. Their only defense is to raise their hair " quills' and swat with their tails. All 4 of my dogs have painfully learned to keep their distance and just bark at one until it leaves, and never to frighten it with no escape route.
