Is it something many pagans do?

I would suggest that no true pagan would act in this manner. certainly no pagan who I know or have encountered would..
Virtually ALL pagans hold ALL life to sacred. Many pagans are either vegetarian or Vegan for this very reason.
Even those who are not veggie or Vegan but omnivourous will decry the slaughter of any living thing for sport.
The man states that he sacrificed to the god of the wilderness in thanks. I know of no pagan ritual that fits this description, but we are talking about the US here and, as I have stated previously, what the pagans and witches in the US have done to what I call paganism and witchcraft in order to, as they put it, "improve them", is horrendous!
