Hirschfelden got a major upgrade when Pheasants were added to it. Pheasants were a great addition to this map, and hunting them in the open fields is quite fun in my opinion. However, I also think that Capercaillie on Hirschfelden would be a great option for more backfilling. They were added to Classic recently and now inhabit Classic's rendition of Hirschfelden (although they are referred to in Classic as the Wood Grouse).
I really think that Call of The Wild's version of Hirschfelden would benefit from the addition of the Capercaillie, since the Pheasants that now occupy this map are really only found in the open fields. Capercaillies could easily be added to the more forested areas of Hirschfelden, giving those areas an upland game bird for players to hunt. Since Layton has turkeys now, why can't Hirschfelden have Capercaillies?
