#aviar

• Avian — Pertaining to birds, relating to birds, or originating from them; it applies specifically to avian viruses, pathologies, habitats, or ecosystems. In medical and epidemiological contexts, the term is widely used in phrases such as avian influenza (bird flu), denoting a highly contagious viral infectious disease affecting domestic and wild birds, which can contextually be transmitted to humans.
• Aviary — A rare neologistic form or linguistic variant for an aviary (or voliere), denoting a huge cage, a specially designed enclosure, or a large greenhouse where live birds are kept, bred, and displayed in conditions close to their natural habitat; it is used in zoological gardens and ornithological parks to ensure flying space for exotic or protected birds. Its root is closely tied to the Latin concept for a bird shelter.
