hey jens,
i hear what your saying. i suppose i have always assumed the form to be a peacock, without giving it a thought to being something else. in a sculpted form, your beak will make it clear. as an engraving, however, this would be less obvious. also, remember not all decorative art is up to the standard of your own collection. i have seen artists of such poor stature that i'm sure they were aiming for a peacock but produced a very ugly duck-like creature that could only be loved by its mother
