Many people enjoy bird watching as a hobby. One way to observe birds is to set out birdseed to attract the birds. There are many different types of birdseed and many different types of birds. Although birds appear to eat anything available, most birds are very picky about what they eat.

In this project, the preferences of neighborhood birds is observed.


ornithology: the study of birds


Different types of birds prefer different types of foods. Even when hungry, birds are very selective as to what they will eat.

Research Questions
  • What types of birds live in the neighborhood?
  • What types of bird seed to different types of birds prefer?

  1. Gather the necessary materials.
  2. Weigh ¼ of a cup of each type of birdseed. Pour the birdseed directly on the scale or be sure to weigh the empty cup first and subtract the weight of the cup to get an accurate weight of the birdseed only. Record the weights.
  3. With the help of an adult, build the bird feeder by nailing the foil trays onto the board.
  4. Pour ¼ cup of each type of birdseed onto its own foil tray.
  5. Place the board with the trays in a convenient spot outdoors. The chosen spot should be easily accessible to birds and easily observable from a distance.
  6. Sit with the binoculars, notebook, pencil, and bird identification resource a short distance from the board with trays. Observe the feeding trays for at least 30 minutes noting what types of birds come to the tray and approximately how long they stay. Note if some birds return or if distracters (such as barking dogs or people) interfere with the birds’ feeding.
  7. After 30 minutes, take the feeding trays back inside and reweigh each of the seeds.
  8. Record the weights.
  9. Repeat Steps 6 and 7 for seven days. Record the data.
