You can buy special bird seeds with hot pepper added to it. For birds hot stuff is just another flavor while other animals will not like the taste and it will burn their mouth.What can you do to stop animals from gettin into my bird feeder?
Can you extend the feeder by putting up a hook that will move the feeder out from the fence so that animals can't reach it?
Without seeing the outlay of your home it's hard to help. The reason I'm ';answering'; is this reminds me of something I saw at someone's home once. The man took a 5 or 10 gal. fish tank and mounted it into his living room window so that the top(open part) of the tank was facing outside (so the tank was laying on it's side) with the tank protruding towards the inside(the living room). He had it all properly insulated around the edges(like an air conditioner would be). He placed bird feed into the tank and you could sit in the living room and watch the birds as they landed in the tank to feed. I thought it was an amazing idea. I hope it is something you can do! Good Luck!! (By the way! The window was high enough up from the ground and there was no trees or fences near it so nothing but birds could access the feeder)
there are feeders out there that prevents animals from getting into bird feeders
