"This is a Zitan bird cage with all the fittings necessary to keep a bird well fed:  little porcelain bird feeders ready to feed the bird.  He would have to be a class-act bird:  this is a zitan bird cage.  Most cages are made of bamboo, this is the only one I have ever seen of zitan. The top has an unusual aspect to it:  a painting of a sparrow by an unknown master.   "^^<http://www.w3.org/2001/XMLSchema#string>
