Beaks

Woodpeckers peck tree trunks with their long pointed beaks and eat insects found there.

Pelicans have large beaks.

The great swans swam round the new-comer, and stroked his neck with their beaks, as a welcome.

Small crows have the largest beaks.

Gulls have strong and fairly long beaks.

Toucans have large, colorful beaks.

The famous white-sand beaches of Hawaii, for example, actually come from the poop of parrotfish. The fish bite and scrape algae off of rocks and dead corals with their parrot-like beaks, grind up the inedible calcium-carbonate reef material (made mostly of coral skeletons) in their guts, and then excrete it as sand.

Scarce out of sight of Sicily, they set / their sails to sea, and merrily ploughed the main, / with brazen beaks, when Juno, harbouring yet / within her breast the ever-ranking pain, / mused thus: "Must I then from the work refrain, / nor keep this Trojan from the Latin throne, / baffled, forsooth, because the Fates constrain?"

Birds have beaks.

Shut your filthy beaks, you fucking birds!
