What does a roadrunner use its beak for?
First, let's talk about how a roadrunner kills its prey.
Let's say it got its beak around a snake. The roadrunner would
then swing the snake around and bash it against the ground until it
was dead. Well, to due this, not just any beak would do. That is
why the roadrunner's beak is very sturdy.
So to answer your question, it has a long beak which is slightly
curved and sharp, as well as sturdy.
