Bird
A bird is a warm-blooded vertebrate animal that belongs to the class Aves. They are characterized by their feathers, beaks, and ability to fly. Birds come in various shapes, sizes, and colors, with over 10,000 different species found worldwide. They have hollow bones, which make them lightweight and enable them to take flight. Birds have a unique respiratory system that allows them to efficiently extract oxygen from the air. They lay hard-shelled eggs and have a high metabolic rate. Birds play a crucial role in ecosystems as pollinators, seed dispersers, and insect controllers. They are known for their melodious songs and are often admired for their beauty and grace in flight.
