Living birds lack teeth, and the jaws are covered by a horny beak, which often shows adaptation to the bird's particular diet: long, slender beaks for probing for insects, flat or paddle-shaped beaks for sieving food out of the water, heavy beaks for cracking and crushing seeds, or sharp, hooked beaks -- like that of the vulture depicted at right -- for tearing flesh.
