Probing beak• The hummingbird’s
beak allow it to sip nectar from flowers. Some birds have probing beaks that allow them to find food in sand or mud.
4
Drilling beak• Also referred to
as a chisel-type beak, a woodpecker can locate and extract insects below the surface of a tree’s bark.
5
Cracking beak• Many birds that
eat seeds must be able to crack open the hull that surrounds the seed. Birds such as finches and sparrows do this.
6
Spearing Beak• These birds have a
beak with serrated edges and a hooked tip that helps them catch fish or minnows. The heron is such a bird.
7
Tearing Beak• Birds of prey such
as the eagle, hawk, falcon, and owl use their beak to tear their food into small pieces they can swallow.
8
Filtering Beak• The bill of a duck
is fringed to allow mud and water to escape while straining plants, seeds, and small animals for it to eat.
