Bull crap.

I’ve seen birds eat all of the above with no ill effect. Most of them do not seem to even have any distinct flavor that would cause anyone to want them, but they probably are healing substances.

I not completely sure how to respond to this...You do realize that birds and humans have rather different physiological makeups, right? Ivy berries for example, toxic to humans but not to birds because birds do not have the receptor on their white blood cells that responds to the urishiol in poison ivy, unlike humans.

Thats also why you don't feed chocolate to dogs.

I'll also say that not all of the berries on the brief list I provided are equally toxic. You could certainly eat some of them in small quantities with relatively minor side-effects. I advise strongly against such a course of action however, and I take no legal responsibility if you go and ingest a pound of yew-berries and drop dead.
