Having used feeders for 30 yrs in Texas I can tell you the noise will not bother any animal. As far as Deer, Turkey and hog go, it's a good attractant when the feeder goes off. Being about half deaf, when I see the birds at the feeder flush, I know a larger animal is coming in to feed. You also can judge an animal and be more selective on your harvest. You can also take some good pictures. If you have Hogs be sure to use T posts to stake your feeder down or the Hogs will turn it over and distroy it.
