There are actually two basic approaches to keeping

squirrels out of your bird feeder. The first is to simply attempt to block them from getting to the feeder. There are two common kinds of feeders that do that. Squirrel proof bird feeders are very common.Baffled Bird Feeder - By simply restricting access to the the food in the feeder, you frustrate them and they move off. The advantage to using a baffle is that it more or less separates the squirrel evidence barrier from the feeder itself, so the bird have unlimited access to the bird seed, and any size bird can still use the feeder. This is commonly done by pole mounting the feeder, and putting the baffle on the pole. Other types use a hanging arrangement and the baffle forms a roof over the feeder. With the top mounted feeder you may also find a squirrel smart enough to climb down and cause the feeder to swing, and while they may not gain access to the feeder itself they could cause the bird food to spill to the ground, where they can get all of the food they want. Caged Bird Feeders - Another common solution is to use a caged feeder. It's a reasonably open mesh, and in fact a tube style caged feeder looks like an electronic bug zapper with the open mesh surrounding the tube. Caged feeders are better at keeping the squirrels out of the feeder, but they can still get to it and shock off the birds that try to use the feeder. This is usually the case when you are making an attempt to attract smaller birds. The second approach to disposing of squirrels in your bird feeder is to move them out. The much better types of squirrel evidence feeders are those that cause the squirrel to fall off or be thrown from the feeder. While this won't harm the squirrels they are fun to look at in action... .
