"Avian" refers to anything related to birds. This term is derived from the Latin word "avis," meaning bird. Avian characteristics include feathers, beaks, and the ability to lay eggs. Birds are found in various habitats around the world, from forests to deserts, and they play essential roles in ecosystems, such as pollination and seed dispersal. The study of avian species is known as ornithology. Ornithologists observe bird behavior, migration patterns, and their interactions with the environment. Some well-known avian species include eagles, sparrows, and penguins. Understanding avian life helps in conservation efforts and maintaining biodiversity.
