* Numbers equal or greater than 5 mean that varriety of SB was able to survive in that environment
** Numbers equalto or greater than 12 mean that varity is able to Trive! i.e. they have energy to reproduce laying5-8 eggs at a time.
Answer the following questions. Use a separate sheet of paper that you will attach to the group data tables
Part 1

  1. Which prey items were preferred (highest yield) by more than one predator?
  2. Could all of these predators coexist in a single habitat? Why or why not?
  3. What happened when resources became limited?
  4. Which predators (beak types) would have survived and likely reproduced more?
  5. Is there a predator in this environment that would have been selected against?

Part 2

  1. How did the change in environment affect the birds?
  2. What types of resources can be limited in an environment? List five examples.
  3. Were particular birds adversely affected?
  4. Did any group of birds do better in this new wet environment?  If so, which ones?
  5. Which birds would likely have more offspring?
  6. Is the effect on the survival and reproduction of these birds an example of natural selection or artificial selection? How are they different?
  7. Does natural selection operate on individuals or populations? Explain.
  8. Can an individual member of a species evolve? Explain.
