He looks like a Percy to me.
When I first got my budgies, in my first post on a parakeet forum I was immediately told to get rid of the perches that came with cage. Nope that didn't work. Instead I got a whittling knife. I put in alternating, irregular divots round about the perches & then smoothed them out, until the original (relatively thick) dowels had been transformed into more irregular, vaguely natural-branch-like perches.
(Based on the description of work needed to use natural pine branches, I think my solution was probably easier.)
In my case, as I went forward & with my Sun Conure having some balance issues, I found the rope perches to work best. I do inspect them, keep them clean, but so far have not had any issues with loose threads etc. Also I have a variety of perching options, include thick store-bought natural branches. IF there is a variety of perches then, as I understand, it is okay to leave in the dowel perches too as just another option he will use occasionally.
I'm so glad you got him!!!
