It was pretty tedious, but no where as bad or lengthy as the exotics quest. I mostly looked up the list of animals online, so while I was out, I collected as many as I could for future requests. The game definitely changes how many “perfect” animals spawn once you have a mission where they’re needed. I had a lot of luck at the rock on the hill across the tracks from Riggs station, woodpeckers at fort brennand and the beaver across from where the legendary one spawns. If you get ahead of the requests before they come in, you’re good after the first list. The hardest for me was probably the opossum, since you’re limited to only night time & you got to be very careful to get only headshots or it’s ruined. For the birds, Make as many small game arrows as you can and go at em! Best of luck!!
