There are a variety of ways to control the kinds of birds that come to feeders. Pigeons, for example will not or cannot eat food from a hanging tube feeder, especially if it contains niger (thistle seed), a favorite of the finches. Blackbirds, European starlings and grackles are unable or cannot eat from a feeder that is up and under a dome squirrel baffle. Most of these large pest birds do not like to eat safflower seeds, a favorite of the Northern Cardinal. Therefore, the kinds of feeders, the locations of the feeders, and the foods offered in the feeders controls the kinds of birds that can or will eat from them.
