3: Classification of Birds | Kingdom: Animalia Phylum: Chordata Subphylum: Verbrata Class: Aves Orders: Flightless birds, waterbirds, birds of prey, and wading birds.

4: Biome sweet Biome

5: Biomes by Class Birds are under the class Aves which contains more than 10,000 species. Birds are normally found in areas where there are not many predators to attack them. Many birds are found in the tropics, the Arctic tundra, and near freshwater biomes. Birds are found throughout the world and where ever they can find food, water and shelter.

7: Reproduction Method of Birds All birds reproduce sexually, and the egg is fertilized internally.

9: Birds Behavior by Orders Birds of prey are usually hunting for food for themselves or their children. Flightless birds are more quiet and if attacked by a predator they flee.

11: Water birds: Water birds have a diet of aquatic life, such as spiders and insects that live in the water, and they also eat fish. Flightless birds: There are 2 different diets of flightless birds. The first is a diet of mostly vegetation that grows close to the ground, and the second is a diet of worms, bugs, and other little animals. Birds of prey: Have sharp hooked beats that tear flesh and claws that grip their prey. They hunt during the day. All eat at least some kind of animal flesh. | Predator/Prey feeding habits

13: Type of Symmetry Like many animals that live on land birds have bilateral symmetry which keeps the bird in balance so it is able to fly and/or catch its prey.

15: The first birds appeared in the Jurassic period. This is in the Mesozoic era around 208 million years ago. | Era of Birds

17: Aptenodytes Penguins belong to the genus Aptenodytes. Aptenodytes usually are found in tundra biomes but the African penguin lives of the coast of Africa so their biome is Tropical Forest. Aptenodytes one type of genus of birds that are flight less and depend on the water for food. Also another thing that all Aptenodytes have in common is that the mother lays the egg but the father carries the egg until it is hatched.

18: Food Web

21: Food and Body Temperature As you have probably noticed bird DO NOT HAVE TEETH! Their beaks are specially designed for the bird and what kind of food it eats. Birds of prey usually have sharp and curved beaks for tearing and shredding meat and long talons for gripping their food. Other birds who eat plants and seed would have a duller tip in their beak and a hard beak for crushing seeds and plants. When a bird eats food it goes through the digestive system and goes into the gizzard which may contain stone that help grind the food since birds have no teeth. Birds are endothermic so they need a lot of energy to keep their body temperature just right. Since birds need so much energy to keep up with daily tasks they eat a quarter of their weight.

23: What is a bird? | A bird is an endothermic animal with a back bone (vertebrate) that has a 4 chambered heart. Birds have feathers and lay eggs.

25: Diversity of Birds Birds may be the most diverse vertebrates on land. With more than 10,000 species there are some many different types of birds. There are big bird, small birds, flightless birds, birds that can fly, and so many more. Birds have adapted differently because they all live in different biomes and eat different kinds of food. Also some birds need camouflage to protect them from predators while other birds have BRIGHT feathers.

26: The air sacs that help deliver oxygen more efficiently. | The four - chambered heart of a bird.

27: Delivering Oxygen to Cells | In order to release the energy that is contained in food, cells must receive plenty of energy. Birds fly, so they need a very efficient way to get oxygen into their body and cells. They have a system of air sacs that connect to their lungs. The air sacs let the birds extract oxygen, and also take oxygen to the cells. Birds have hearts with 4 chambers with 2 atria and 2 ventricles. Oxygen rich blood doesn't mix with oxygen poor blood. This helps blood that arrives in the tissues to have lots of oxygen.

29: How does air move over their wings? As you can see it the image to the left air gives some kind of force(pressure) and can keep an animal from flying. The faster air moves there will be less pressure on an object so if the air moves faster on the upper surface of the wing and moves slower on the bottom of the wing you have something to push off of which creates lift and allows birds to fly and continue to fly. People have used the structure of bird wings to help create an airplane that can fly.

31: How Birds Reproduce and Care for Their Young | The eggshells that birds lay are harder than reptile eggs. Usually the female lays her eggs in a nest that one or both of the parents made. Vultures and falcons don't build nests. In order for the eggs to hatch, the parent will sit on them and keep the eggs warm. The length of time for an egg to hatch varies, depending on what type of bird egg it is. Sparrow eggs take around 12 days, while albatross eggs take somewhere around 80 days to hatch! Birds of prey usually lay their eggs in the early spring or summer. and the male hunts for prey while the female takes care of the newly hatched bird.

33: Nervous System Birds must react quickly to their surroundings. They need fast reflexes so they can capture food, fly and escape predators. Without their quick reflexes a bird would die very quickly. Also birds have extremely good eyesight to help them see food.

35: Why Birds are Important | Birds lay eggs, which are a source of food and protein, and the feathers are used to stuff pillows and are found in jackets and clothing. Humming birds carry pollen from flower to flower, and enable flowers to reproduce. Birds that eat seeds carry seeds to new places, where a new plant can grow. Birds also feast on MANY pests such as mice, rats, and insects.
