A haunting, highly detailed image of a horrifying ghost bird flying with its wings fully spread. The spectral creature has translucent, ethereal feathers that shimmer with a faint, eerie glow against a dark, ominous background. Its eyes are hollow or emit an otherworldly light, and its sharp beak and talons add to its menacing appearance. Trails of mist or wisps of ghostly energy follow in its wake as it soars through a night sky filled with swirling fog or over a desolate, moonlit landscape. The overall atmosphere is chilling and unnerving, capturing the terrifying presence of the ghostly bird in vivid detail.
