What kind of beak does a kookaburra have?

The kookaburra has a sharp, strong beak. It needs such a beak as it is carnivorous. Apart from feeding on insects, it also swoops down and collects small mammals and reptiles. In particular, it can often be observed carrying a lizard or snake to a branch or a rock on the ground and, holding the creature in its strong beak, the kookaburra will then proceed to beat the reptile or mammal on the branch or rock until it is either dead or close to it, whereupon it can eat it.
