An Abnormality from Project Moon's works (Lobotomy Corporation, Library of Ruina, Limbus Company), appearing in Lobotomy and Library as of 01 Apr 2025.

Bird of Judgement[sic], also simply called "Judgement Bird"[sic], appears as a tall, lanky bird-like creature with a bandaged head and a crooked neck, upon which rests a deliberately-unbalanced scale. It is closely tied to two similar avian Abnormalities, Big Bird and Small/Punishing Bird. In Lobotomy it is a WAW-class Abnormality (second-highest on the game's threat scale) and can combine with the other two birds to create another Abnormality, Apocalypse Bird. In Library the birds are associated with the Binah floor and are fought both as individual Abnormalities and collectively as part of the floor's Realisation boss fight.
