California squirrels are eating rodents in broad daylight.
In California’s Briones Regional Park, researchers observed a startling new behavior: California ground squirrels, typically known for eating nuts and seeds, are now hunting, killing, and consuming voles, a smaller rodent species in their habitat.
A study in the Journal of Ethology documented 74 squirrel-vole interactions, with 42% involving squirrels stalking, pouncing on, and eating voles. This behavior, observed almost daily, marks the first recorded instance of widespread carnivory in this species. While squirrels have occasionally eaten insects or bird eggs, actively hunting warm-blooded prey is unprecedented.
Student-recorded videos show squirrels chasing voles, restraining them with forepaws, biting their necks, and consuming their flesh or organs. The behavior may stem from a vole population surge—nearly seven times the state’s ten-year average—prompting squirrels to exploit this abundant protein source.
Squirrels of all ages and sexes participated, suggesting a potential lasting adaptation. It’s unclear if this carnivorous trend will continue once vole numbers normalize, but the discovery reveals the surprising adaptability of even well-known animals.

@Mossan841121 リポストありがとうございます🙇
レイモンドに匹敵しているのはヒューストンのレインくらいですね。互いに保存の良さの方向性が違うので甲乙をつけがたいです。

@iNmiruka11235 今はわからないけど、2025時点では展示されてたよ-w(今はわからないけど)
地味に知られてないのは、パキの装飾、一部は皮骨が形成してる点で、それが科博の展示で明確に見えるんだよね。赤丸の上に、皮骨が乗ってたハズ。
原始的な種にはみられない特徴、どの進化段階で獲得したのかなぁ?

@NS_Museum This is a demonstration website - but for #FossilFriday you can also see the skull of Teraterpeton in 3DVR - turn and zoom into the skull to explore the details at: edinos.ca/VR3/
