Found this in my favorites. For those of you who make your own wood toy parts or use natural branches for perches, this is a good reference.

Arty.... I just happened to notice that Firethorn is toxic on your list and safe on the other list. Anyone know for sure? I did not yet check closely all the names on each list & compare to the other lists.

So I am wondering now, how are we supposed to really know if any of these lists are really accurate - seeing this discrepency for example?

I've noticed these sort of discrepancies before. I tend to look at several of the lists, and make sure what I'm looking for appears as safe on all of them. It doesn't do a lot for your confidence though, does it?

It sure doesn't. I know apple is safe, but on some sites I'll see it listed as unsafe. I think they might list it that way to cover all bases thinking the fruit trees have a possibility of being sprayed. I've also seen some sites get very explicit. Exp: Some trees, the bark is toxic, or the leaves but the actual wood isn't.

Also note... because this is a world-wide web some trees will have different names in different English speaking countries.

For instance "madrona/madrone" is what we in BC call an "Arbutus".

I'm not sure if there are others in the list that fall into that issue as well.

I didn't consider that- thanks for pointing it out!

I thought EUCALYPTUS wasn't safe for birds?

If you go to the link in the first post, it is on the safe list with a side note:

Sorry, that's the extent of my knowledge on it!
