This module was adapted by the addition of outside resources listed in the attached file.

How does a bald eagle population change over time at a winter migratory stopover and which factors influence its abundance?

This activity has two different aspects to the learning style:

  • Guided Approach: Students will generate questions abut bald eagle numbers influenced by weather and food availability.  Students will then use graphing software (JMP of Excel) to compile the data in a graphical form to answer their questions.
  • Open-Ended Approach: Students will generate their own hypothesis of interest from the larger bald eagle data set.  This approach is encouraged for upper division ecology students in conservation biology, wildlife management, or population ecology classes.
