Bai Baianai (Old Turkic: 𐰉𐰀𐰖 𐰉𐰀𐰖𐰀𐰣𐰀𐰖) is the Yakut spirit of forests, animals and patron of hunters.
Baianai is most often described as being a blonde, tall and slender woman with pale, glowing skin and fiery eyes.
They have the powers to bring about drought, burn a farmer's crops or make cattle die of high fever.
It is said that when a Baianai is angered she would change her appearance and turn into a monstrous bird, capable of flinging fire at her enemies.
According to folk beliefs, Baianai lives inside huge old trees, in abandoned shacks or dark caves, near rivers, ponds or wells.
