Corpse-Weepers (Nakikabane, ナキカバネ) are a type of monster from Made in Abyss.

They are large birds that live in the 2nd layer of the Abyss, in the Forest of Temptation.

Corpse-Weepers are carnivorous and quite violent at that. They are notorious for their capabilities to mimic sounds and use it for hunting. If they capture prey with high social capabilities such as Hammerbeaks or humans, they will learn their prey's cries for help and use it to lure others to their colony, thus giving them the name,
