This is one of the less endearing fashion trends of the Victorian era; the use of animal parts to create jewellery. The collection of hummingbirds for their feathers and for taxidermy decoration put some species of hummingbird at risk at the height of the practice. The use of hummingbirds to create fashion accessories is now illegal, and that is okay with me. I find the idea of hunting down tiny birds for ornithological jewellery rather distasteful, as well as the use of other animal parts for ornamentation.
This is why I prefer modern Steampunk jewellery that uses resin models or metal casts of skulls for ornamentation. I find these items much less creepier and more ecologically sound than the Victorian version.
