Avian biology is the study of birds, focusing on their anatomy, physiology, behavior, and ecology. Birds are warm-blooded vertebrates characterized by feathers, beaks, and the ability to lay eggs. They belong to the class Aves and are found in diverse habitats worldwide, from forests to deserts. Research in avian biology also explores topics such as bird migration, reproduction, and social behavior. Scientists study various species to understand their adaptations and roles in ecosystems. This field contributes to conservation efforts, helping to protect endangered species and their habitats.
