FC: All About Birds and How they fly | by: Anna Nguyen and Harrison Daniell
1: Classifying Birds | Kingdom | Animalia | Phylum | Chordata | Sub Phylum | Vertebrata | Class | Aves | Orders | Raptors, Flightless birds, nocturnal birds, songbirds, water birds, wading birds,seed eaters, insect eaters
2: Characteristics | Raptors | Aggressive and predators | Flightless Birds | strong running and flightless | Water Birds | Can swim and eats things in and around water | Wading Birds | bad swimmers and long legs | Small and herbivorous | Seed Eaters | Insect Eaters | mini raptors! | Predators of night | Nocturnal Birds | Songbirds | Small and most numerous | Behaviors
3: How do birds reproduce? | Birds reproduce internally and sexually. The female first fertilizes the egg internally, and then lays the egg. One or both parents take turns to incubate the egg. If the egg isn't kept warm, the egg won't be fully developed and won't hatch.
4: Biomes | The class Aves lives almost everywhere on the planet. | Water Birds and Wading Birds live mostly in and around water | Songbirds, Seed Eaters, and Nocturnal Birds live in wooded areas
6: Life of a Prey... and Predator | Birds don't have teeth, or fingers, or hands. So how do they get their food? Each bird has their own kind of beak that varies on their environment. The shape of each bill helps each bird obtain the food they need.
7: For example, a woodpecker has a sharp, pointed bill used for drilling holes into trees so they can get their prey.
8: Symmetry of a Bird
9: Bird's have bilateral symmetry. This is an adaptation for them because when birds fly, both sides of their bodies must be the same. For example, if one wing was long than the other, the bird would keep flying in circles because one wing is longer than the other.
10: The Discovery of the Bird | The first bird to appear on Earth was the Archaeopteryx. This bird appeared in the Jerassic Period in the Mesozoic Era.
11: The Archaeopteryx
13: The Food Web | It all falls into place. If one part of the web is taken out, every other animal that eats it will die out too because their food source is gone. As you can see, the bird is at the top of the food chain.
14: When birds fly, how does the air move across their wing?
15: When they start flying, air moves above and below the wing. The air flowing above the wing has a lower air pressure than the air flowing below the wing because the faster the air flows, the lower the air pressure. This is because the lower part of the wing is flatter than the upper part. The shape of the wing helps the bird because if the higher air pressure is underneath, the bird will start rising. The low pressured air doesn't push down on the wing as much as the high pressured air pushes up.
16: FLYING BIRDS | How Birds Take Off: Step by Step | 1) They push off the ground with their legs. 2) They stick out their wings while they jump forward to catch some wind.
17: 3) Once they're off the ground, they have to start flapping their wings to get up in the air. This is harder for smaller birds because their wing span is short and can't get enough air to get high enough.
