  • 1. Animal Adaptations A Closer Look at Bird Beaks
  • 2.
    • Finches have different beaks and eat different foods
      • seed eaters have thick, heavy beaks
      • fruit eaters have short stubby beaks
      • insect eaters have sharp, pointed beaks
    • differences in finches’ beaks are adaptations to food they eat
    • adaptation: a body part or behavior that helps an animal meet its need in its environment
  • 3.
    • all birds have beaks that help them get food from their environment
    • there are many other adaptations
      • size of an owl’s eyes/shape of hawk’s claws
    • all birds have the same basic needs
      • different adaptations to meet those needs
    • feathers are an adaptation
      • keep birds warm, dry, and help them fly
      • feathers are very light and give bird’s body smooth surface so air passes over it easily
  • 4.
    • hollow bones are another adaptation
      • bones filled with air pockets
      • make birds light
    • flightless birds have adaptations
      • ostrich – long legs and 2 toed feet let them run about 40 mi/hr
      • penguin – everything from beak to feet adaptations for swimming
  • 5. Body Coverings
    • every animal’s body covering is an adaptation the helps them survive
      • feathers protect birds and help them fly
      • fur/hair keep mammals warm
        • some mammals have sharp hairs for protection
        • some have whiskers that are used as sense organs
      • fish have scales to protect them from disease and other animals that live in the water
  • 6.
      • reptiles scales protect them from injury and drying out
      • snake scales overlap to form a smooth covering that helps them move
  • 7. Color and Shape
    • camouflage : an animals color or pattern that helps it blend in with its surroundings
      • an adaptation helps an animal hide
        • snowshoe hare is white in winter and brown in summer
          • change in color makes the hare difficult for other animals to hunt because it blends in
  • 8.
        • tiger’s stripped fur helps it blend in with the light and shadows of the tall grass of its environment
        • toads have bumpy brownish skin to make it look like a pebble
        • chameleon’s color changes to match its surroundings
        • alligator’s back makes it blend into the swamps
    • mimicry : an adaptation in which an animal looks very much like another animal or an object
      • viceroy butterfly looks like a monarch butterfly
        • monarch butterflies taste bad to birds
        • birds avoid viceroy butterflies
  • 9.
      • walking stick looks like a twig
        • birds don’t see it as a bug to eat
  • 10. Summary
    • animals have adaptations that help them meet their needs
    • adaptations include body coverings and the shapes, sizes, and colors of body parts
