My discussion about birds
Birds (Latin, Spanish, Portuguese, Italian: Ave, German: Vogel, English: Bird, French: Oiseau) There are some insects and fans of feathers, but only birds have feathers. There are approximately 10000 species of birds in the world. In general, all living birds belong to the Neurithic group. Birds of the class (Aves) have been formed in 23 classes, 142 species, 2057 masses and 9702 species. [2] However, new species are constantly being discovered and new species are identified by dividing older species. Fossils available so far indicate that the birds appeared in the Jurassic period, about 16 million years ago. According to paleontologists, the only descendant of dinosaurs of four-colored dinosaurs, birds of the Cretaceous-Palaeogene extinction half a billion years ago Among the living birds, the hummingbird is smaller (only 5 centimeters or 2 inches) and ostrich is the largest (2.75 meters or 9 feet.
