Classroom Feeder Watch program of the Cornell Lab of Ornithology is a research and interdisciplinary education curriculum designed for students in grades 5-8.Through this program students learn how science and scientists work, become scientists themselves, collect data on feeder-birds and contribute it to a research database used by professional ornithologists in their studies of bird populations.

Background for Teachers

Instead of using hands and forelimbs to perform survival tasks, birds have a unique tool: their beaks. Birds use their beaks as multi-functional tools to groom feathers, weave nests, attack rivals, defend territories, communicate, and most importantly, to capture or gather food. A wide diversity of bird beaks have evolved over time.

Each bird 's beak creates a survival advantage which allows that bird to reproduce and pass its inherited traits on to the next generation. For example, the heron and the woodpecker both have long pointed beaks. However, the heron's beak is better for catching fish, while a woodpecker's is better for drilling into wood for catching insects. Over time, herons have become more numerous in marshlands than woodpeckers. This is why it is so hard to find a woodpecker feeding in marshland. It simply does not have what it takes to survive in that environment.

Hummingbirds feed on flower nectar and are attracted to red, tube-shaped flowers. Consequently, they need a beak that can fit into those flowers and a long, tubular tongue to collect the nectar. Seed-eating birds, such as cardinals, have short, thick beaks enabling them to break seeds open as easily as a nutcracker. Some birds have frail beaks that would break if they tried to crack open a hard seed. However, they have large mouths that more than make up for their weak beaks. Purple martins and whippoorwills use their over-sized beaks to catch insects while in flight. Their mouths function like huge insect nets.

While some birds, such as hummingbirds, are food specialists, others are food generalists. Blue jays, for example, eat berries, seeds, grains, nuts, insects, fruit, snails, frogs, small birds, salamanders and eggs. Their ability to eat a wide variety of food provides a survival advantage by enabling them to live in a greater variety of environments than food specialists. However, they may face more competition for each type of food.

Intended Learning Outcomes

1-Use science process and thinking skills.
2-Manifest scientific attitudes and interests.
3-Understand science concepts and principles.
4-Communicate effectively using science language and reasoning.

Instructional Procedures

Invitation to Learn:

  1. .Bring a variety of carpenter and woodsman tools and set them on a table.
  2. Tell students that finding food, shelter, clothing, and water are basic to survival needs.
  3. Ask students: If you were sent to a deserted island with only one of these tools, which one would you choose? Remember, the tool you choose would be the only thing you had to use to collect food, build shelter, make clothes and collect water.
  4. Have students discuss what they would choose and what survival advantage it would give them.
  5. Now ask students: Would you choose a different tool if you knew you were going to be left in the jungle, the mountains, or the arctic? Have them discuss how each environment would affect their choice of tool.
  6. Tell students they are going to participate in an activity which demonstrates how birds use their beaks as one main tool in survival.

Instructional Procedure:

  1. Divide the class into groups of 4-5 students.
  2. Distribute one different type of “beak” (tool) to each student. Instruct students to hold the tool with one hand and put the other behind their backs.
  3. Place a “stomach” (cup) in front of each student.
  4. Place one type of food at each group's feeding area (paper plate). Instruct students that, at your signal, they must compete for as much of that particular food resource as they can gather with their “beaks.” All food MUST go into their cups. Remind students that their survival depends on their ability to gather food.
  5. Give the signal and allow the group one minute to “feed.” After saying, “Stop!” have students discuss which beak was most successful in gathering what type of food.
  6. Repeat this procedure at least three more times, each time with a different “food” source. Have students discuss their experience after each stop signal.
  7. Have each student sort the food in their “stomach” into piles. Have each group construct a data table to record how much of each food type they collected for each type of beak. Also have them list which bird(s)had a survival advantage with each food item. Compare and discuss the data gathered by the different groups. Were any of the beaks food specialists? Food generalists?
  8. Ask the students to compare each food item to things that birds really eat, such as insects, worms and seeds.
  9. Have students use the Bird Identification Sheet to find which bird beak most resembles their tool. For example, a student who had a pair of pliers would identify the Evening Grosbeak.
  10. Using a bird identification book (such as National Audubon Society's Guide to North American Birds) or other resources (see “Additional Resources” below) have students write a short paragraph on a particular bird's environment and what specialized structures give it a survival advantage in that environment.


Prepare a bird observation area by hanging one or more bird feeders near a classroom window. If using multiple bird feeders, use different types of food to attract different types of birds. Have a bird identification book and a pair of binoculars placed where students can use these tools for observation and identification.

Integrate social studies concepts by having students examine Old and New World plants and animals. Did these plants need to adapt to new climates and conditions or were there greater changes in the culture of the people? Use the Internet to find information on Teosinte, a native grass that was changed over time to eventually become maize, a staple for the Native American diet.

Have students explore how a changing environment provided different survival advantages for the English peppered moth. These moths occur in two forms: a light gray form with dark splotches, and a uniformly dark form. Peppered moths rest during the day on trees and rocks encrusted with light-colored lichens which camouflage the light form, but expose the dark form to increased predation by birds. Before the Industrial Revolution, the dark moths were very rare. Pollution from the Industrial Revolution darkened the countryside in the late 1800's, killing the lichens. In this changed environment, the dark moths were concealed from birds, and the light moths became very rare.

Assessment Plan


  1. Why can a large variety of birds eat in the same geographical area?
  2. Do birds use their beaks for purposes other than eating?
  3. Are birds adapted to certain geographical areas according to beak structure?
  4. How do a bird's feet help it to eat? What other survival advantage may a bird have according to the type of feet it has?
  5. What might happen to a bird population if its environment experienced a natural disaster where all the flora or fauna were wiped out?
  6. Are we as dependent on food sources in our environment as birds are in theirs? Are other animals? Are plants?
  7. Could migration patterns be linked to survival in a certain environment? (Yes, some animals move because of the climate, while others migrate because a food source moves to a different climate for better survival chances. Then predators follow them.)
  8. Why don't farm animals exhibit survival advantages like wild animals? (They have been domesticated and rely upon people for their food, shelter and care.)


This lesson is part of the Fifth Grade Science Teacher Resource Book (TRB3) The TRB3 is designed to be your textbook in teaching science curriculum to your students. This book covers all the objectives of each standard and benchmark. If taught efficiently, a student should do well on the End-of-Level (CRT) tests. The TRB3 is designed for teachers who know very little about science, as well as for teachers who have a broad understanding of science.
