Immense Riches of the Birds World
Birds constitute an exclusive assemblage of highly specialized vertebrates, typified by fluff, feather and flight. They descended down from their reptilian ancestors some 140 million years ago and their earliest known ancestor was Archaeopteryx. Then a rapid evolution followed and as of now 8,498 species of birds, scattered over 23 orders, with bizarre sizes, shapes, vibrant hues and acoustic varieties, live around the world
The current monograph boasts of a panoramic view of birds way of life. Bird's life, dazzling silhouettes, superb nesting and territorial behaviour constitutes a distinct class.
