I have a budgie, sun conure and Hahn’s macaw. All 3 of them love these, though it took the budgie and macaw longer to start chewing on it. It is relatively easy to chew and shred, which made it really fun for them. We tied some onto our toys as add ons, some we slotted through perches. It’s great for our out of cage perches as it gives the birds something other than furniture to chew on!
