Beaks are horny, projecting structures that form the mandibles of birds. They are generally strong, sharp, and useful in striking and tearing. The beak’s function varies significantly from species to species; it can be used to kill prey, probe for food, manipulate objects, groom, or feed young birds, and its size and shape vary accordingly. Though beaks are worn down over time, they grow continuously throughout the birds’ lifetimes. What species of bird uses its beak to “kiss” during courtship? Discuss
