Open wide! Your teeth are your friends -- how could you eat without them? But what about wildlife? Some have teeth, some have bills. What's in their mouths helps determine what they can eat.
Do birds have teeth and lips? No, but look at the many shapes of their bills! The shape of the bill helps them eat. What birds have bills like a nutcracker? How does it help them eat?
|A Woodpeckerís bill can
chisel into trees in search of sap and small bugs. This is a Pileated woodpecker.
|The Acorn Woodpecker of West Texas will actually pound acorns into trees to eat later! Almost 50,000 acorns were found embedded in a single tree!|
|The Cardinalís bill is thick and cone-shaped, and as strong as a nutcracker. Itís perfect for sunflower seeds.|
|The cardinalís cousin, the painted bunting, has a similar bill. Both
cardinals and buntings forage on the ground and in shrubs for a tasty meal of
berries, bugs and large seeds.
|See the narrow, tweezers-like bill on this Warbler? It can easily hold tiny seeds, small bugs and berries. It often feeds in low trees and shrubs.|
|Perhaps youíve seen the Great Blue Heron at the waterís edge. Its sharp bill has serrated edges and a hooked point to spear and grab fish and frogs. It may grab a fish sideways, then use its long bill to toss fish in the right direction to slip down its throat.|
|The Hummingbird's long, thin bill acts like a straw to probe deep into flowers and sip nectar.|
|Dabbling ducks like this mallard have bills with comb-like edges that act like strainers, separating plants, mollusks and insects from the water.|
|This skimmer flies low over the water with its bill open. Its longer, lower jaw slices through the water in search of fish.|
|One of the most distinctive bills belongs to the Roseate Spoonbill. It swishes its spatula-like bill back and forth in the water to find food. The sensitive tip of its bill will snap shut when it feels prey.|
|Pelicans have great scooping
bills and can carry three gallons of small fish in their pouches!
Birdsí bills are marvelous tools made especially for the food they eat. The next time you see a bird, look at the shape of its bill and see if you can guess whatís for dinner!
