Birds

Michael Weeks

       Birds are vertebrates,this means that they have a backbone.Most birds can fly but a select few are flightless like the ostrich, emu,and penguins. Birds are in the class Aves. The feathers they are covered in are special to them no other animal has them. They act like a barrier from sun water and heat  loss they also provide a smooth surface for the air to push against when flying. The two hind legs are for climbing, nest building,or swimming.The beak is designed to aid in the picking up of small insects and seeds which is the most common diet of birds.

     The characteristics of birds were acquired by modern birds through evolution, adapting to the environment they are in. For example birds with smaller beaks are able to get into smaller insects shelters while birds with nigger beaks are able to break and carry larger nuts to their nest.Birds also have camouflage suited to the environment they live in,for example a finch in North Carolina may be brown with some color due to the lack of bright colored plants, while a finch in Hawaii may be vibrant and full of color due to the colorful plants there. Birds feet also tell about there evolution, some species of sea birds have webbing in their feet for aid in swimming when hunting while a bird from the rainforest has longer toes and nails for holding on to a branch.
