Perhaps, in the spirit of Monty Python, this was an "ex-parrot" (i.e. deceased but presented as if it was alive)? Or perhaps the photo was digitally altered? The ruffled feathers around the photographer's hand seem a bit off to me (or perhaps it's just my el-cheapo laptop monitor). The shadows look correct but the ruffles seem...off.
If so, it's pretty funny
Or perhaps the guy was really holding a live bird as depicted and he (the guy, not the bird) is simply a jerk.
