"Fitcher's Bird" (German: Fitchers Vogel) is a German fairy tale collected by the Brothers Grimm, tale number 46.
It is Aarne-Thompson type 311, the heroine rescues herself and her sisters. Another tale of this type is How the Devil Married Three Sisters. The Brothers Grimm noted its close similarity to the Norwegian The Old Dame and Her Hen, also grouped in this tale type.
The tale also features the motifs of the "Forbidden chamber" and a bloodied item that betrays the bride peeking in that chamber against strict orders, and as such bears resemblance to the Bluebeard type tales (which are type AT 312).
A sorcerer would take the form of a beggar to abduct young women as his would-be brides. After bringing the eldest sister of a family back to his home, he assured her she would be happy with him. Eventually, the sorcerer leaves but not before handing her the keys to all the rooms the house and an egg to look after that was to be on her person at all times. However, he forbade her to enter one particular room in the house under the penalty of death. Ultimately, the sister did investigate the forbidden room out of curiosity and discovered a basin of blood at its center. Shocked at the dismembered body parts that existed within it, she dropped the egg.
Once back home, the sorcerer could tell by the bloodied egg that the sister had gone against his will in his absence and had her suffer the same fate as the others from the room. Subsequently, a second sister from the family was carried off only for the same outcome to occur as that of the first. It then came to be that the youngest sister found herself in the very same situation. But unlike her sisters, the youngest had put aside the egg before exploring the house. In the forbidden room, she found and assembled her sisters' remains which united and brought the sisters to life again.
Finding her egg unstained upon his return, the sorcerer was ready to marry the youngest sister. Freed from his power, she had the sorcerer carry a basket of gold back to her family without rest. She indicated that she would be watching from a window at his progress while she would make preparations for a wedding. Unbeknownst to the sorcerer, the voice that would scold him whenever he tried to take a break on his journey came from one the two sisters hidden inside the gold-brimmed basket and not his bride.
