From the San Francisco Chronicle:
If it quacks like an alien ...Looking at our three ducks in a new light... That might explain the bright lights at night.
Unidentified facelike object peeks out from duck X-ray at wild bird rescue center
As if crop circles weren't proof enough that extraterrestrials are among us, an alien has now been found in the stomach of a duck.
That, at least, is the conclusion reached by workers at the International Bird Rescue Research Center in Cordelia (Solano County) when they viewed an X-ray image they took of a sick mallard.
Right there, in the duck's ventriculus, or gizzard, is the shocking image of a grimacing, bald-headed being. How it got there, nobody knows, but when an autopsy was performed after the bird died of unrelated causes, the alien had mysteriously disappeared.
"We're a 35-year-old organization, and we've seen a lot of things -- bullets, fish hooks -- but this is the first time anything like this has shown up," said Jay Holcomb, executive director of the bird rescue center, which was founded in 1971 after an oil spill beneath the Golden Gate Bridge. "I don't know my aliens well, but it looks like one of those with the big eyes and the long fingers."
The drake in question arrived at the center Sunday with a broken wing. Workers do not know how the mallard was injured, but it was clearly weak and emaciated. In an effort to pinpoint the trouble, Maria Travers, the assistant rehabilitation manager, took a radiograph image of the bird. She was stunned by what she saw.
"Look at this," she shouted. "It's an alien head!"
Holcomb admitted the strange image could have been an odd arrangement of grain in the stomach, similar to the anomalous "Face on Mars" photographed by the Viking Lander when it orbited the Red Planet in 1976.
Not only to they eat slugs and icky bugs, they protect us from aliens. What good critters they are!
