Bird mummy's secret: Why raptor was force-fed by ancient Egyptians

Its last meal wasn't pleasant.

A mouse tail was lodged in its throat when it died. Semi-digested flesh and fur still remained in its stomach when it was wrapped in mummy bandages.

A new autopsy reveals that overeating choked and killed this unfortunate raptor from ancient Egypt. Scientists suspect that Egyptians force-fed the bird so they could offer it to the sun god Ra as a votive mummy.

Mummification wasn't reserved for people in Egypt. The archaeological record is full of examples of cats, dogs, crocodiles and birds that were mummified and used as religious offerings to their corresponding animal gods, a practice that was popular from about 600 B.C. until around A.D. 250, well into the Roman period. Salima Ikram, a professor of Egyptology at the American University in Cairo, has made a living studying these animal mummies, and for her latest research, she examined the ancient remains of a European kestrel from the Iziko Museums of South Africa in Cape Town.

New imaging technologies have made it possible to see through mummies without butchering ancient corpses: Ikram and her colleagues used an X-ray computed tomography scanner at Stellenbosch University in South Africa to see the insides of the kestrel in 3D. The images revealed the bird's stomach was stuffed with bones and teeth from at least two mice —one with its tail inside the raptor's esophagus —and a partially digested sparrow.

The kestrel's skeleton showed no signs of trauma. And whereas other bird mummies in Egypt had their gizzards removed or their beaks packed with food after death, this specimen also had no signs of evisceration. The kestrel was likely desiccated with natron (a naturally occurring soda ash) embalmed with resin and wrapped in bandages (in this case, quite haphazardly) with its stomach contents intact.

"We were extraordinarily surprised by the virtual autopsy as we had no expectation of any contents within the kestrel's body," Ikram said. "To learn that it choked was amazing."

Ikram and her colleagues say it's unlikely the kestrel accidentally or deliberately ate itself to death, as the birds are known to store food when they catch too much for a single meal. Rather, the bird likely had lots of help dying from its captors.
