42. Study the illustrations of bird heads and feet on page 226 of the study guide. Using what you have learned in this unit about how organisms occupy niches in ecosystems, design two birds
that could occupy two different niches in the same ecosystem. Choose a head and feet for
each and describe them in the space provided below. (Note: Be sure your head and feet go

A. Bird One:
B. Bird Two:
C. How their niches are different:
