The Ga'Hoolology chaw is a chaw of The Great Ga'Hoole Tree. It specializes in caring for the great tree. The activities they perform include pellet burying, vine trimming, and pruning. When the band first arrived at the tree, the chaw was instructed and run by the Burrowing Owl Dewlap. It was viewed by most owls as the most boring subject and chaw. However, when Otulissa took over students tended to like the subject more, and become more interested. For those who are tapped for the Ga'Hoolology chaw, Otulissa offers a class about the natural history of the great tree.The milkberry is the symbol for the Ga'Hoolology chaw.
