A study led by the University of Wisconsin-Eau Claire (US) has discovered that California ground squirrels (Otospermophilus beecheyi), previously considered herbivores, exhibit opportunistic omnivorous behavior.  

  • Researchers observed the squirrels hunting, killing, and eating voles (rodents), with 42% of 74 interactions involving active hunting.  
  • The squirrels' carnivorous behavior peaked in early July, coinciding with a surge in vole numbers, indicating their hunting was triggered by an abundance of prey.  
  • It revealed that squirrels' diets are more flexible than previously believed, helping them adapt to changes in food availability and survive in rapidly changing environments. 
  • California Ground Squirrels: 
    • It is also known as the Beechey ground squirrel and commonly found in western US. 
    • They have mottled fur, with gray, light and dark brown, and white present in their pelage. 
    • They are commonly preyed upon by rattlesnakes, eagles, raccoons, foxes, badgers, and weasels and can live up to 6 years in the wild. 
    • IUCN Red List: Least Concern 
    • CITES: No special status 
  • The Indian palm squirrel (Funambulus palmarum) is commonly found in India and Sri Lanka.
