There are several types and styles of bird feeders. Many people want to just watch birds or they want to help entertain their indoor cats.
The best way to choose a feeder is to pick one that matches the type of birds in your yard. Many bird feeders are made to attract or feed different kinds of birds. Some feeders are for birds to eat close to the ground and others are elevated on a platform.
For the beginner, a hopper-style feeder in the shape of a house is a reasonable choice. Once you have a feeder, make sure you choose the seed that works best with it.
