Hackerbats were creatures found in the Deepwoods. They were probably related to Oakbats and Cavebats. Hackerbats roosted in trees, living close to snowbirds. They chattered and chirruped when disturbed or in panic. A flock of hackerbirds flew in panic when Mother Muleclaw the Third and her Shryke Sisterhood traversed the Deepwoods in Freeglader.
