Dec. 18 (UPI) — California floor squirrels that scientists thought ate solely grains are consuming voles, too, in response to researchers at University of California-Davis and the University of Wisconsin-Eau Claire.
“We had by no means seen this conduct earlier than. Squirrels are one of the vital acquainted animals to individuals,” Jennifer E. Smith of UW-Eau Claire mentioned in a UC Davis assertion. “We see them proper outdoors our home windows; we work together with them often. Yet here is this never-before-encountered-in-science conduct that sheds gentle on the truth that there’s a lot extra to study concerning the pure historical past of the world round us.”
Smith added it was “stunning.”
According to a UC-Davis assertion on the findings, “The squirrels’ carnivorous summer season conduct peaked in the course of the first two weeks of July, coinciding with an explosion in vole numbers on the park reported by citizen scientists on iNaturalist. This means that the squirrels’ looking conduct emerged alongside a brief improve within the availability of prey, the research mentioned.
Smith and different scientists noticed the squirrel’s meat-eating conduct June 10 to July 30.

She added as soon as they began wanting the researchers noticed that conduct practically daily.
“Voles (have come to) acknowledge the squirrels as predators,” mentioned John Koprowski, dean of the Haub School of Environment and Natural Resources on the University of Wyoming, who wasn’t concerned in then the research. “There’s doubtless some actually neat interaction between the 2 species as a result of being eaten is often not an effective way to proceed passing in your genes.”
The scientists by no means say the squirrels consuming different mammals, solely the voles.
According to Smith California floor squirrels are “unimaginable opportunists.”
The analysis staff needs to know extra concerning the squirrel conduct and plans to return into the sphere subsequent summer season to attempt to see how widespread the looking conduct is and the way it’s handed down from mother or father to pup.
