My mother once freaked when I ate some mystery berries (which turned out to be wild rasberries) because she thought they were yew berries. If they were, would I have gotten sick? Birds eat them, but I'm assuming they'd be immune to any toxicity.
- It's actually the seeds inside the berries that are toxic. The ripe berry itself is harmless. Other parts of the plant, such as the leaves, are also highly toxic. That said, I wouldn't recommend eating the berries anyway - firstly because the toxin is powerful and you don't want to make a mistake (especially not swallowing a seed by accident) and secondly, because you should never trust everything you read on the Internet.
