I used to hear this a lot — that (red European) squirrels are cute, but they take bird eggs! Then I started seeing, from lots of sources that should be reliable, that squirrels are in fact vegetarian, and that there little or no evidence of them taking eggs or animals. And then this article shows up, and I no longer know what to believe. Was "squirrels are vegetarian" a cover-up by Big Squirrel?
