Bird anatomy, specifically the physiological structure of birds' bodies, showcases numerous unique adaptations, primarily to facilitate flight. Birds possess a light skeletal system and lightweight yet powerful musculature, along with circulatory and respiratory systems capable of high metabolic rates and oxygen supply, enabling their ability to fly. The evolution of a beak has led to a specially adapted digestive system in birds. Their skeletal system comprises many hollow (pneumatized) bones with criss-crossing struts, providing structural strength. The vertebral column of birds is divided into five sections, including cervical, thoracic, synsacrum, caudal, and pygostyle, each serving specific functions related to flight and mobility. Additionally, birds are the only living vertebrates to have fused collarbones and a keeled breastbone, which serve as attachment sites for the muscles used in flying or swimming. These anatomical adaptations collectively contribute to the remarkable aerial abilities and diverse behaviors observed in avian species.

Bird flight is the primary mode of locomotion used by most bird species, enabling them to feed, breed, avoid predators, and migrate. It includes various types of motion such as hovering, taking off, landing, and gliding flight. Over millions of years, different bird species have evolved specialized wings and forms of flight to adapt to specific environments, prey, predators, and other needs. The basic mechanics of bird flight involve lift, drag, and thrust, similar to aircraft. Birds use mainly three types of flight: gliding flight, flapping flight, and bounding flight, each distinguished by different wing motions. Some bird species, such as hummingbirds, are specialized for hovering, requiring considerable energy expenditure. The evolution of bird flight has been the subject of various theories, including flight from falling or gliding, from running or leaping, and from wing-assisted incline running. Understanding the complexities of bird flight provides valuable insights into the natural world and the adaptations that have allowed birds to thrive in diverse environments.

Bird wings are specialized forelimbs in birds, equipped with feathers to facilitate flight. They vary in shape and structure depending on the bird's flight capabilities and environment. Terrestrial flightless birds, like the moa, have reduced or absent wings, while aquatic flightless birds, such as penguins, use their wings as flippers in water. The anatomy of bird wings includes the shoulder, forearm, and hand, with the hand being significantly transformed to support flight. The finger identity problem in bird wings has been a topic of debate for years, with various hypotheses proposed to explain the discrepancy between anatomical, paleontological, and molecular data.The shape of a bird's wing plays a crucial role in its flight abilities, with different wing types offering various trade-offs in speed, energy use, and maneuverability. These types include elliptical wings, high-speed wings, high aspect ratio wings, and soaring wings with deep slots. Each type is adapted to specific flight behaviors and environmental conditions. For example, elliptical wings enable tight maneuvering in confined spaces, while high aspect ratio wings provide high flight efficiency for long-duration flights. Different bird species have evolved wings tailored to their specific needs, from fast-flying birds like falcons and swifts to larger inland birds like eagles and vultures.
