Foraging Worksheet

```Name: Chloe Robb
Section # 30
Exercise 2 - Foraging
Summarize the number of turns in your lab section where students survived but did not reproduce. Also,
the number of turns students reproduced, and the total number of offspring produced. Write the results
on the white board, and determine the class average for each turn. Record the data in Table 5. Example: if
18 chip clip birds in your lab section survived out of 24 students, 18 would be entered in the 1st column.
18/24 = 0.75 = 75% class survival. This would be entered in the second data column.

1. Compare (discuss) similarities and differences between your individual results to the class results. Were
you, as an individual, a successful forager? Why or why not? (2 pts)
2. Which foraging strategies worked well, and which did not work well, and how did beak shape affect
different foraging strategies? What could you (the birds that you represented), have done to improve your
foraging success? (2 pts)
3. Which birds were the most, and least, successful? Where they generalists or specialists? Discuss the
differences and the pros and cons of being a specialist versus generalists (incorporate your results and
information from the lab discussion). [3 pts]
4. Take a photo or scan page 9 from your lab manual and insert it here: [2 pt]
