Many avians have strong historical makeup cultures, even though the current skimmer majority stigmatizes it as dishonest and probably Gay. Piercings and such are fairly uncommon because avian bodies are pretty delicate and bad at handling injury. Nostril and beak rings are seen instead of piercings, especially among diver avians, and are usually clamped on. The dominant skimmer culture has strong emphasis on conformity and singular ideals for appearance, so countercultures tend to be really out there and aggressive in their presentation. Some of the weirder things avian punks will do is feather plucking (partial or whole body), feather splitting or decorative clipping, full body dyeing and painting; or any sort of injurious mod, like ear-notching and piercing. Avian ears are very rigid and well suited for elaborate patterns of removed chunks, even if the medical tech that allow such modification to happen is very recent.
