Antic shops, Christmas shops, Specialties (glass items) shops can be a source for old fashion long (ripped tube) like ornaments that will just fit an Amazon Wing or tail feathers. Difficult to find, and if you see them, do not look at the price, just buy them, cause you will likely never see them again and will regret not getting them. Oooh, look for Blown Glass Artists shop that custom make on-sight! We had visited one in the Detroit Michigan area twenty years ago and saw, but didn't buy! Got lucky years later.
We purchased four at a Christmas shop in Christmas Michigan like eight years ago! Today, we wished that we had gotten a dozen!
Hmmm... I do get the occasional very small yellow, red or microscopic blue one, but I never see feathers that small off him that are that small. His wing and tail have the multicolor ones. He's mostly all green on the body though. What species of amazon are those from?
Like I said, either macaw or amazon... quite possibly all macaw. Even then, I couldn't tell you which bird exactly. These feathers came from a rescue and rehome place for parrots and the feathers weren't kept separate.
