Squirrels not only eat seed from bird feeders, but squirrels also scare birds away. So even if you have a weight-activated “squirrel-proof feeder”, you might still want to baffle it to keep squirrels from jumping on it and frightening birds away.
If you hang a bird feeder from a tree, you need the best hanging squirrel baffle you can get. Squirrels can eat most of the food you put out for birds unless you use a truly squirrel-proof feeder or a really good squirrel baffle or better yet, both. Don’t just buy whatever you see labeled “baffle” and expect it to work. Here is what to look for in a good squirrel baffle.
