Dark Souls 3 has a crow’s nest that allows you to trade in items to get different items from a hidden crow perched on the roof of the Firelink Shrine. While it’s possible to reach the crow’s nest without the Tower Key, it’s best to spend 20,000 souls so you can purchase the Tower Key from the Shrine Handmaid.
From the main entrance to the Firelink Shrine, head up the stairs to the right (facing toward the shrine). When you reach the top floor, there are three window-like archways to the right, with a tree outside wrapped in a statue. Head outside and up the stairs to the left of the tree, then turn around to see an item corpse on the rooftop. Depending on your weight it is possible to make the jump onto the roof, but if you have the Tower Key, there’s a much easier way to get to the item corpse (which only holds three Homeward Bones).
With the Tower Key from the Shrine Handmaid, open the gate and head up the stairs. When you reach the top, head across the bridge. About halfway across there’s a broken portion the bridge that allows you to move down slightly. From here you can drop down to the top of the stone support pillar and move safely down to the roof below.
Head to the immediate left and knock down the ladder so you have an easier time accessing this area in the future. In the middle of the roof is a nest where you can trade items with a hidden crow in exchange for other items. To use the item exchange, stand in the nest and select an item from your inventory to leave in the nest. It's important that you select Leave and not Discard, or else the item will be lost for good and you won't get an item in return. Here are all of the items you can get from the crow’s nest exchange.
