Title: Bird%20Beaks%20


1
Bird Beaks Their Uses
2
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.
3
Griffon Vulture
DIET Feeds on large dead mammals, taking only
muscle meat and viscera. Their distended crops
and gizzards can hold over 13 pounds of meat at a
time.
4
Hook Beak
  • Birds that eat fruit, berries, and vegetables
    have a hooked beak to help them dig into their
    food.

5
Yellow-Naped Amazon Parrot
DIET Fruits, seeds, nuts, berries, blossoms,
and probably leaf buds.
6
Red-Billed Hornbill
DIET Obtains almost all food on the ground
while running about. Feeds largely on insects -
beetles, grasshoppers, termites, ants, fly
larvae. Also takes geckos, birds' eggs and
nestlings and scavenges dead rodents.
7
Chestnut Mandibled Toucan
DIET Primarily fruit and berries, but
supplemented with large insects, small reptiles
and amphibians, as well as the eggs and young of
other birds.
8
Blue Yellow Macaw
DIET Seeds, fruits, nuts and probably
vegetable matter.
9
Spear-like 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.

10
Hammerkop
DIET Hammerkops feed on frogs, fish and
invertebrates.
11
Louisiana Heron
DIET fish, crustaceans, and insects using their
beak much like a spear.
12
Pelican
  • DIET fish

13
Crackers 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.

14
Speckled Pigeon
DIET Mainly a ground feeder. Feeds on seeds
and cultivated grain.
15
Sparrow
  • DIET seeds with hard shells, sometimes flowers,
    insects, spiders, and berries.

16
Tweezers Beak
  • Birds that pull worms and insects from the ground
    need tweezers-like beaks.

17
American Robin
DIET earthworms, grubs, butterflies, cherries,
and blueberries
18
Straw-like Beak
  • The hummingbirds beak allow it to sip nectar
    from flowers. Some birds have probing beaks that
    allow them to find food in sand or mud.

19
Hummingbird
  • DIET nectar

20
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.

21
African Spoonbill
DIET Insects, larva, shellfish
22
Wood Duck
DIET plants, seeds, grasses and other small
insects and animals that they find on or under
the water.
Aix sponsa
23
Lesser Flamingo
DIET Herbivorous, feeding solely on Spirulina
plantensis, one of the blue-green algae growing
within a very limited range of pH 10.4 - 10.5.
They are surface feeders filtering the top inch
or two of water where the spirulina is to be
found with the deep-keeled bill that is
specialized for very fine food particles. They
swim well and are able to forage over the
complete surface of a lake (the "swim and skim"
technique).
24
White-Faced Whistling Duck
DIET Invertebrates such as aquatic insects,
mollusks and crustaceans as well as aquatic
plants, seeds and rice. Commonly obtain food by
diving.
