The Surprisingly Complex Science of Bird Longevity. How long do birds live? Whether you want to ace this question at your next bird-themed trivia challenge or just impress someone spontaneously, here's the answer: Birds can live between four and 100 years, depending on the species.
Birds have a two part stomach, a glandular portion known as the proventriculus and a muscular portion known as the gizzard. Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and starts the process of breaking down the structure of the food material.
Many of the bones in a bird's body are hollow, making the bird lightweight and better adapted to flying. Birds also have feathers that make flight easier. Long feathers on the wings and tail help birds balance and steer and other feathers provide insulation and protect birds from the sun's ultraviolet rays.
