The only animals that the flash has spooked around here are coyotes. Deer, hogs, foxes, bobcats and others don’t deem to pay it any attention. I have had many, many sequences of flash pictures, 30 seconds to a minute apart, day after day, showing the same animals feeding with no concern whatsoever.
Plus on several occasions I’ve witnessed the camera taking flash pictures of deer and hogs without the slightest disturbance to them. On the other hand coyotes are good for one picture. When the flash goes off they hit the road, at a rapid rate.
