Birds are warm-blooded vertebrates with feathers, beaked jaws, and a unique anatomy adapted for flight, including a lightweight skeleton and complex respiratory system. They exhibit diverse behaviors, communicate through visual and auditory signals, and play significant roles in human culture and economy.
