Birds are warm-blooded vertebrates classified in the class Aves. They are characterized by feathers, beaks, and the ability to lay eggs, making them distinct from other animals. Birds play crucial roles in ecosystems, acting as pollinators, seed dispersers, and indicators of environmental health. Their anatomy is specially adapted for flight, with lightweight bones, strong muscles, and efficient respiratory and circulatory systems.
