George of the Jungle won't have anything on your birds! If you can't bring your birds to the jungle, bring the jungle to your birds! See my birds having a great time on theirs! Stiff enough to hold shape as a natural boing w/ smaller birds (see Goffins). All natural, USA grown, 15+ foot grape vine rope. 1.5 inch diameter. Leave at this length or cut to your own desired size. A swinging good time for everybirdy! I have mine going ALL the way across the bird's room.
