We create temporal loops in time which anyone can live indefinitely... only women are born ymbrynes... We ymbrynes must scour the countryside for young children in need, steer clear of those who would be harmful, and keep our kind fed, clothed, hidden, and steeped in the lore of our people. And if that isn't enough, we must also keep our loops resetting each day like clockwork.

–Miss Peregrine

Ymbrynes (pronounced imm-brinn) are female peculiars who can manipulate time and can take the form of a specific bird. Ymbrynes take care of peculiar children to hide them from wights and hollows by creating time loops that can be accessed by other peculiars. They are usually places that provide safety from the outside world.


  • Avian Shapeshifting: Ymbrynes are able to shift into a particular species of bird.
  • Time Manipulation: Ymbrynes are able to manipulate time and create loops.
  • Memory Manipulation: Ymbrynes are able to manipulate other people's memories and certain memories, such as erasing them.


The first known ymbryne was a bird that turned into a woman. She went by the name of Ymeene. She died at 157 from the Bubonic Plauge. In America, the majority of the ymbrynes were killed by normals, hollowgasts, and wights. The Organization was created to killing ymbrynes. The ymbrynes in the south got the first and worst of it. In the 1860s, an ymbryne maintained four or five loops at a time, and most of the peculiars barely got to see her. Gradually, ymbrynes all over the nation started disappearing. A few ymbrynes may have survived, but they don't have anything like the power or influence they used to.

  • Grimbears are the preferred companion of ymbrynes in Russia and Finland.
  • While in the books, clothes do not go along with the ymbryne when they change into a bird, but in the movie they do.
