Recently, a badly injured mallard duck was brought to the agency which rehabilitates water fowl.

During a routine X-ray of its stomach, workers were shocked to see what appeared to be the head of an extraterrestrial alien.

"It looks like a tiny alien in his belly, that's about all I can say," International Bird Rescue Center spokeswoman Marie Travers said. "No Elvis sightings that I've heard of yet."

A necropsy of the duck indicated that the alien image was mostly likely a lump of grain.

The X-ray will go on the virtual reality auction block to raise money for the bird rescue center.
