I actually just finished reading the CA apprentice manual and study guide. Before that I read the DNR packet. My recent purchase was A Falconry Manual by Frank Beebe. My next purchase (next paycheck) was going to be either The Falconer's Apprentice or a Peterson Field guide. I am not really sure what I should look at after the Beebe book. I am trying to be knowledgeable for taking the exam. The recommended reading on the MN DNR is really outdated (commissioner's words not mine) so I am not really sure. She didn't have any recommendations for what I should be reading.
