Flock of Killer Birds are monsters in the facility. They not listed on the whiteboard or shown during the Purge.

 They can breifly be seen during the elevator scene circling in their cube cell.

Appearance and CharacteristicsEdit

The birds are depicted as normal, ordinary looking birds, but with a want of killing the innocent. They are similar in concept to the Rabid Dogs, in that they are not supernatural in appearance, but are based on real world horror themes.

It is possible that an eagle figurine summons them.


They are probably a reference to Alfred Hitchcock's The Birds, where swarms of killer birds attack a small, helpless town. Other films where birds kill people include Killing Birds and Birdemic: Shock and Terror.
