DID YOU EVER WONDER WHY SO MANY BIRD BEAKS?

short, thick cone-shaped beak (bill) for cracking
seeds.

curved bill for tearing meat (prey)
4
Chisel Type
  • Woodpeckers have bills that are long and
    chisel-like for holing (boring) into wood to eat
    insects.

Probe Stlye
  • Hummingbirds bills are long and slender for
    probing flowers for nectar.

Strainer type
  • Some ducks have a long, flat beak that strains
    small plants and animals from the water.

7
Strainer (contd)
  • Along the inside of the beak they have tiny rows
    of plates called lamellae like a whale's baleen.
    These let them filter water out of the side of
    their beaks and keep food inside.

    beaks adapted for fishing

Tweezer Type
  • Insect eaters like warblers have a thin pointed
