I live on six mostly wooded acres of land so the cheapest for me is to cut a limb from a bird safe tree or to replant a smaller entire tree in a 5 gallon bucket and let them have that. You could probably find a larger already potted tree at a nursery if they have any that are bird safe that they have not sprayed with any chemicals.
For my GCC, I actually made a table top playstand out of a wicker basket. It works great for small birds, is extremely portable, and you can get wicker baskets pretty cheap at secondhand stores. Just avoid anything that's been painted.
I made a large table top ply jym with Apple wood and had leaders and bells on it I would post a picture but it's says its God too many pixels. Pvc pipe idea is pretty cool but it doesn't look the nice and it's really smooth so parrots would slip and it's the same diameter which wouldn't be good science my lorikeets are out for more than 7h
Parrotkeeper02 there should be a way to reduce the size of your phot in your photo editing software that is on your computer. for the purposes of size 1 kb is about the same as 1 pixel just reduce the longest side of the picture to 630 pixels reducing the other side the same amount of pixels as you reduce the long side and then it should load here.
The easiest way I found to reduce photos on an ipad is to email them to yourself. When sending it gives you sizing choices like small, medium, large. Download the ones in the email and they are smaller than the original.
