But walking down the street where those fumes are in the air at low concentrations, we feel safe to breath. As noted, Birch should be considered safe and the risk of leaving bark is inconsequential.
i copied this from a wood/tree/plant site for parrots.
so basically yes...it is safe as long as the bird and branches are not in an enclosed space
hope this helps!

I think the automotive comment is a reference to the salicyate content (being of a low concentration in the tree branch, as opposed to an aspirin tablet, much like a running car in a closed garage can kill you, but standing next to the road won't) not about keeping the tree in an enclosed space...
