Bird Adaptations

 

It’s For the Birds!  

 

Introduction:

Did you ever wonder why there are so many types of bird beaks (scientists call them bills)? The most important function of a bird bill is feeding, and it is shaped according to what a bird eats. You can use the type of bill as one of the characteristics to identify birds. Here are some common bill shapes and the food they are especially adapted to eat:

 

SHAPE TYPE ADAPTATION
Cracker Seed eaters like sparrows and cardinals have short, thick conical bills for cracking seed.
Shredder Birds of prey like hawks and owls have sharp, curved bills for tearing meat.
Chisel Woodpeckers have bills that are long and chisel-like for boring into wood to eat insects.
Probe Hummingbird bills are long and slender for probing flowers for nectar.
Strainer Some ducks have long, flat bills that strain small plants and animals from the water.
Spear Birds like herons and kingfishers have spear-like bills adapted for fishing.
Tweezer Insect eaters like warblers have thin, pointed bills.
Swiss Army Knife Crows have a multi-purpose bill that allows them to eat fruit, seeds, insects, fish, and other animals.

 

Another characteristic that can be used to learn more about birds is feet shapes! The shape of the feet reflects the habitat that the bird will be found in and the type of food it might eat. Here are some common feet shapes and the environment they are especially adapted to live in:

 

SHAPE TYPE ADAPTATION
Grasping Raptors like Osprey use their large curved claws to snatch fish from the water.
Scratching Pheasants and other birds that scratch the soil for food have nail-like toes.
Swimming Ducks and other webbed lined swimming birds use their feet like paddles.
Perching Robins have a long back toe, which lets them grab a perch tightly.
Running Many fast-running birds have three toes rather than four.
Climbing A woodpecker’s hind toes enable it to climb without falling backward.

 

 

Objective:

Students will observe adaptations of feet and beaks of birds and relate these to the bird’s method of feeding and to the bird’s environment.

Materials:

Lab paper, pictures of birds, pencil

Procedure:

  1. Look at the pictures of the birds. Examine the beak of each bird and determine the type of each beak based on its shape and function. Some beak types may be used more than once.
  2. Place your choices on the chart in the column marked Beak for: (Some of the same beaks may be found on different birds).
  3. Examine the pictures of each bird and determine the type of feet each bird contains.
  4. Place the name of the bird on the line that best describes their type of feet.
  5. Also place the foot type on the chart in column 3 titled Feet for. (Some foot types may contain more than one bird.)

Questions:

  1. Birds living near lakes, pond or the ocean are most likely to eat the following organisms.
  2. If you see birds walking around a lawn in front of your house, what types of things could serve as a food supply for these birds?
  3. Explain why dead or diseased trees can serve as a food source for some birds.
  4. Based on the talons found on an eagle, what type of beak would it contain?
  5. A hawk looks like it has perching feet. What type of claws does it contain based on the hooked beak?
  6. Which bird contain the longest legs? What type of food do you think it eats?
  7. If you found a bird with climbing feet, what type of food would you expect it to eat?
  8. How many of there birds live near water? How can we tell?

Build a Bug

 

Build-a-Bug

 

Introduction:

Most adult insects have the following characteristics:

    1. A body divided into three parts (head, thorax and abdomen)
    2. Three pairs of legs
    3. Usually one pair of antennae and a pair of compound eyes (a few exceptions to these characteristics are found)
    4. Usually two pairs of wings (absent in many insects such as lice, fleas, ants; flies have one pair of wings)

There are approximately 30 orders of insects. Choose one of the insects from these orders.

INSECT ORDERS

Click on the link to learn more about the characteristics of that order. There are links to specific insects on each page.  Visit the Field Guide Index to see a listing of all insects featured in the Field Guide.

Objective:

Students will build biologically correct insects in order to learn insect structure and adaptations.

Materials:

Any non-food item such as cardboard, egg cartons, clay, wire, felt, Styrofoam, pipe cleaners, nylon stockings, pipe cleaners, paint, glue, string, etc.

Guidelines:

  1. Your model must be an INSECT (i.e. no spiders, mites, ticks, centipedes, or millipedes, please). Note: Your insect does not have to live in the United States.
  2. Your model must be between 6-12 inches long, and sturdy.
  3. Be accurate when building your model (appropriate proportions, true color and form, etc.).
  4. The more detail your model has, the better.
  5. A written description must accompany your model and include:
  • The common name of the insect
  • The name of the order to which it belongs
  • A brief description of the insect’s habitat
  • Where the insect is located geographically
  • At least 2 interesting, and unique facts about the insect you have modeled (i.e. “it has 6 legs and 3 body segments” doesn’t count)
  • Your name and address on model description
