"deatharium" ! Thalia...very funny!
A ficus would be a nice choice for your little birds, Finchlet! They are very slow growing trees that come in a variety of leaf shapes and plant shapes. These are the trees that you see a lot of in offices. They range from very tree-like to the rubber tree, which is a ficus too but has big flat leaves.
I have the ficus "Benjamina", which is a very nice little tree. I bought mine very small. You should be able to find a nice size variety in your garden stores or even in your Home Depot or Lowe's store. Their care is very simple and the only thing that might happen if they are shocked is that you would get a massive leaf drop. Some of them get a very interesting root ball that makes the tree look almost bonsai.
Your finchies would probably adore the multi-branced tree....I have no idea how you would keep it clean, though, with those messy little poopers!
