There is a Eagle marker Southeast of Copperhead Rail Yard, East of Roberts Cabin on the top of the hill (west of the Cougar marker). Also find them is Raptor Peak in the North East of Faith's Region. There are about 6 to 7 that fly around at the top and you may have to shoot the civilians otherwise they will kill the eagles and they will fall off the mountain and be a pain to find and skin, they Eagles disappear after you complete the Prepper Stash on Raptor Peak.
You can kill the animals using your "Specialist" that you have assigned by aiming with
and then using either
to have your specialist attack. Be careful not to use anyone in a plane or helicopter because they will damage the skin and I am not 100% sure if that still counts or not.
I had Boomer with me because he is good at spotting animals I may not notice and I also used him to chase down animals I wounded. I used the 50 cal Sniper because it is a insta head shot kill on most animals except Bears it took 2 shots.
For the fish refer to
