Feeding Kookaburra’s by hand! They’re beaks are super sharp and they spin their heads really fast and it makes a clacking sound. They are huge birds, with very good eyesight. Thanks Trevour and Leigh! Feeding Kookaburra’s by hand! They’re beaks are super sharp and they spin their heads really fast and it makes a clacking sound.
