Birds have a lightweight and streamlined body, allowing them to fly. They have two wings and two legs, with the front limbs modified into wings for flight. Birds come in various sizes, shapes, and colors, with over 10,000 different species known to exist. They inhabit diverse habitats worldwide, including forests, deserts, grasslands, and oceans. Birds have a unique respiratory system that allows them to efficiently extract oxygen from the air, enabling them to sustain flight for long periods. They have a highly developed sense of vision and hearing, which aids them in finding food, navigating, and communicating with other birds. Birds play a crucial role in ecosystems as pollinators, seed dispersers, and controlling insect populations. They are also known for their melodious songs and intricate mating displays.
