It's time to learn how to hunt. Walk up the path towards the green circle on your map and when you get there, look around for a rabbit. Draw your bow the same way you would ready a firearm and when you are ready, shoot the rabbit to kill it. Go up to the rabbit and hit the B/O button to skin the rabbit and retrieve your arrow as well.
After killing the rabbit, find the tree nearby with the clue marker above it. Go up to that spot and investigate that marker. When you are prompted to do so, open your tool wheel and use the left stick to select the Snare tool. Place your snare at the base of the tree and then go and find some bigger game.
On your map will be another large green circle. Make your way over to it and investigate the area to find a berry bush marked as a clue. Check it out to find out that a dear had been here recently. The dear will be marked on your screen by a red circle. Get close to it by using the shrubs nearby and when you get to the edge of the shrubs, use your tool wheel to select bait. Use the bait to draw the dear the rest of the way over to you. When it's close enough, get close enough to attack it with your hatchet and kill it.
With some dear meat and a pelt in hand, head back to your snare and you'll find that a rabbit has been caught in your snare. Skin the rabbit. When that has been done, you will split up and try to cover more ground. It is now time to practice what you've learned. Look around the area for clues of animals, use your snares and weapons to get some meat.
There are a few constraints here that you want to keep track of. The first is the variety constraint. You need to kill at least three different animals but if you kill five animals and complete the main objective before doing this, you won't be able to do it. You also need to get two air assassinations and catch an animal by using a snare and bait combo.
To use the snare and bait combo, it's best to use that on a smaller animal like a rabbit or fox. Find some shrubs, drop some bait and then set a snare on top of it to catch one of those animals. Next, find your way into the trees by climbing a cliff or a tree stump and get two air assassinations on a dear and whichever animal you haven't killed yet (fox or rabbit). This will satisfy all three constraints. If you haven't, then you still have two more kills to clean up whichever one you missed.
With your food in hand, track down your friend and be ready. There's a bear chasing after him and you're going to have to get away. The bear will charge at you and you'll have to dodge out of the way similarly to how you handled the wolves as Haytham. When you've dodged and have control again, start running away and head back for the village gate.
When you get there, you'll see what you've both managed for game and head into the village.
