I wondered what kind of bird food would attract the most different birds. I placed two different kinds of bird seed into two cylindrical bird feeders. I observed the feeders 7 times in the morning and at noon for 4 weeks. I watched the feeders by standing near a window. I found out that more birds (20) came to the peanut feeder while 16 birds came to the sunflower feeder. The peanut feeder attracted black capped chickadees, northern cardinals, blue jays, white breasted nut hatches, and red bellied woodpeckers. The sunflower feeders attracted black capped chickadees, American gold finches, northern cardinals, blue jays, and white breasted nut hatches. Next time I would like to study if different types of feeders attract more birds.
