Mob of the Maroon Magpie
From Jenny Everywhere Wiki
The Mob of the Maroon Magpie was one of the Strangely-Colored Secret Societies of the Prime Universe.
The sentient magpies that made it up were among the creatures genetically engineered by Professor Scarper of the First Horde using a mutagen initially developed to create creatures loyal to the Horde. Even after the Horde stopped funding Scarper's experiments, erasing all knowledge of themselves from him or them, this meant that Scarper's creations were compelled to form Strangely-Colored Secret Societies of their own. The magpies followed this pattern, arranging themselves into the Mob of the Maroon Magbie. (PROSE: The Strangely-Colored Secret Societies)
