Document Summary
Essay- why birds are the most wonderful creatures. Birds are special kind of animal species with certain specific characteristics that are common to all of them. They are one of the most wonderful creatures to ever exist. All of them are feathered, winged, bipedal, egg-laying, warm blooded, vertebrate animals belonging to the class aves. They are an important part of the ecosystem and are present across the globe from the arctic to the antarctic. They inhabit the environment that suits them and that is what separates the species found in polar regions from those in the tropical region. In spite of all the similarities that the bird species share, they have certain unique characteristics which differentiate them from others. They could be small as much as 2 inches (e. g. bee hummingbird) to as big as 2. 75 meters (like an ostrich). Fossil records indicate the emergence of birds to as old as 160 million years ago.
