There are 8,600 species of birds in the world today. They are found everywhere. Birds play a vital role in the balance of nature. They eat insects, pests and small animals. Fruit eating birds are best for scattering seeds for these plants. Seed eating birds digest seeds and in so doing keep millions of weeds from the earth. . . . Birds have between 1,000 and 25,000 feathers.
