Beaks • • • Probing – hummingbird Drilling – woodpecker Cracking – macaw, finch Spearing – great blue heron Tearing – hawk Filtering - duck 2
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. 3
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. 4

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. 8
