7 The edges of a Mallard's bill are fringed to filtering out animal or plant material from the water. The combs on the sides of the bill catch the food which is then removed with the tongue and swallowed.
9 Flamingos feed in much the same way as ducks, by taking in a mouthful of water, closing the bill, and forcing the water out by pushing with their tongue. Small shrimps and other animals are caught in the comb-like structures on the sides of the bill.
13 Thin, slender, pointed beaks are found mainly in insect eaters Thin, slender, pointed beaks are found mainly in insect eaters. They are used to pick insects off leaves, twigs, and bark. This warbler is agood example.
17 Hawks, owls, and other birds of prey which catch and kill live prey have sharp, "hooked" beaks. These are used to bite the skull or neck and also to tear the body into pieces small enough to swallow.
18 Since birds have no teeth they either swallow the food whole, or bite, crack, or tear it into bite-sized pieces. They often hold the food with their feet as they work at it with the bill. Birds prepare the food before eating by removing hulls from seeds or inedible parts from prey. Instead of chewing their food, they swallow it in pieces and it is ground up in their gizzard. The gizzard is a muscular organ just past the stomach. It has a hard, ridged inner surface. Birds swallow sand, and small stones. These stay in the gizzard and are ground against the food to break it up.
20 The Skimmer, has probably one of the strangest bills The Skimmer, has probably one of the strangest bills. They feed by flying just above the surface of the water with the open knife-like lower jaw cutting through the water. When a fish is encountered the jaw snaps shut.
22 Beaks which are flat and wide at the base are found in birds which catch insects in flight, such as flycatchers. These birds also often have whiskers at the corners of the mouth, which effectively widens the mouth opening, allowing more effective capture of prey.
24 This Long-billed Curlew, like other shorebirds, has a long narrow bill for probing in mud and sand for insects and worms. The tip of the bill is very sensitive so the bird can feel when it touches its food. In some of these birds the tip of the bill can open to grab the food even when the rest of the bill stays shut.
