Once at the top of the tower, the player must drop from the middle of a partially crumbled bridge and onto the shrine's rooftop. From there, the Nestling can be accessed either at her nest, or directly below it by entering through a skylight on the front.
Alternatively, the Nestling can be accessed from the very first moment one sets foot on Firelink. Make way to the bell tower and run toward the nearby tree, which allows to climb it a little; jump to the right while at the highest point and try to land on the rooftop (many attempts may be required). From there, just look for the skylight on the front and walk along the rafters until reaching the Nestling's secondary trading spot.
- Unlike in Dark Souls, the player is not required to quit their game to initiate an exchange with the Nestling. They simply must drop an item that can be traded and the one given in return will appear immediately.
- Additionally, one may drop any number of items at once and they will all be exchanged properly unlike in Dark Souls where items could only be traded one at a time.
- Teaches the "Call over" gesture upon trading an Avelyn, Coiled Sword Fragment, Divine Blessing, Eleonora, Hidden Blessing, Homeward Bone, Loretta's Bone, Mendicant's Staff, any Sacred Chime, Shriving Stone, Undead Bone Shard or Vertebra Shackle. The gesture will be taught alongside the traded item, and only for the first instance.
- Each trade can only be done once per playthrough. Carvings will only be awarded once per character.
- Pump-a-rum stands for "bumpy and rough", in a similar way as other birds in the series have asked for items like "warm and soft" and "smooth and silky".
