Ooooh…just stumbled over this and thought I would share. 
The University of Minnesota Raptor Center has a section of lesson plans related to raptors! I especially liked the ones involving math and graphing of data.

You may not have guessed, but I have a particular fondness for raptors.
This looks so fun! Thanks for the link!
