There are over 9700 different kinds of birds

These intresting creatures are found all over the world

Birds range from 2 in to over 8 ftThe ability to fly makes them seem

the fastest animals in the world, the fastest birds flying at over 100 mph

All birds hatch from eggs, have feathers, beaks, and wings Beak used for

calling, eating, breathing, etc.

Wings used for flight, body temperature control, and attracting mates.

Birds adapt to their environment depending on their traits and requirements. Different birds require

different needs according to different foods, different ways of getting around, and different behaviors

(Example: A pigeon can adapt to a more urban environment because it can eat many different kinds of food.)

Lift is the main factor of a bird’s flight. An inclined plane is one of the main

factors in a bird’s flight. Hold out your hand like the wing in the picture in the wind. First you will feel the rising force, then drag.

*Another factor is their lightweight skeletons of hollow bone. Their skeletons are lighter than their wings, which helps greatly in flight.

This picture shows the skeletal structure of a basic bird. Notice its backbone.

Flightless birds are birds that have evolved to the lack of being able to fly and instead, rely on running or swimming to get around

There are over 40 known species of flight less birds including ostriches, kiwis, cassowaries, and penguins
