We built a formerly 14'x4' play structure fir our parrots from local grapevine. I say former because over the years the size diminished to 8 ft to 4ft. long. But the various levels of mature grape vines provided the thick perches for our macaw as well as thinner perching for our parakeet and cockatoo. Grape vies are non-toxic. Manzanita is a very hardwood and non-toxic. There is a nother wood whose name ecapes me. It is hollow with many holes Iwill try to find a pic of my play structure and post it next...
