Squirrels are opportunistic omnivores. That’s fancy scientist speak for “they will eat anything that doesn’t run away fast enough.” Nuts, seeds, fruit, fungi, and yes—birds. Especially eggs, nestlings, and even adult birds if the chance arises.
Now, before you start picturing a squirrel version of a T-Rex, let’s be fair. Most squirrels prefer an easy meal. Bird eggs are like protein capsules with a shell—no chasing, no fighting, just cracking and slurping. Studies by the Journal of Mammalogy have documented ground squirrels and tree squirrels raiding nests with surgical precision.
But wait—do they hunt adult birds? It happens. I’ve watched a fox squirrel stalk and pounce on a sparrow that was busy bathing in a puddle. The sparrow got away, but only because I yelled and scared the squirrel. The look it gave me said, “Dude, I was working.”
Why do they do this? (It’s not because they hate birds.)
It’s about survival—especially during spring and early summer. Baby squirrels need high-energy food to grow, and a single bird egg packs more protein than ten acorns. When winter is harsh or nuts are scarce, squirrels become desperate. They’ll chew through plastic bird feeders just to get to the suet, and if a sleepy bird is in the way? Lunch.

And here’s the irony: we humans inadvertently help them become assassins. By putting up bird feeders, we concentrate birds in one spot. Squirrels are smart enough to learn that where birds gather, there might be eggs or vulnerable chicks nearby. Your cute feeder becomes a squirrel’s buffet line.
I’m not saying you should panic. Most squirrels don’t specialize in bird-killing. They’d rather steal a sunflower seed than fight a mother blue jay—those things are vicious. But don’t be naive. A hungry squirrel sees a nest the same way you see a pizza delivery: a hot opportunity.
