About 9,000 different species of birds exist today in our world. They come it all size, forms, and colours. There are brightly coloured parrots and macaws in tropical America, and large cassowaries that cannot fly in Australia. Tiny warblers and sparrows are found in temperate America, and ducks, bastards and cranes in India. Gulls and vultures soar though the skies the world over. Plump chicken and turkeys are found in farmyards everywhere.
