Minnie Woolsey (born in 1880) was an American sideshow entertainer/film performer. In the 1932 film called Freaks, she was billed as Koo Koo, the Bird Girl. Woolsey suffered from an extremely rare birth defect syndrome, resulting in short stature and bird-like physical characteristics.
Woolsey’s Rare Disorder
Woolsey had a rare inherited disorder called Seckel syndrome (also known as bird-headed dwarfism, Bird-headed dwarf of Seckel, and Harper’s syndrome). The condition causes growth delays prior to birth which result in not only low birth weight, but also unusual physical features.
