Every bird is different, but mine tends to like shreddable things and foraging toys.
If you want to buy, these have been the best purchases I’ve made so far: - Planet Pleasures Octopus Piata Bird Toy, Large https://a.co/d/8ch2Cw5 - KATUMO Bird Foraging Toys,... https://www.amazon.com/dp/B0B74WB7NT?ref=ppx_pop_mob_ap_share - Super Bird Creations SB632... https://www.amazon.com/dp/B003HM1WEG?ref=ppx_pop_mob_ap_share - KATUMO Bird Toys, Bird Foraging... https://www.amazon.com/dp/B093SM8CBL?ref=ppx_pop_mob_ap_share
I also regularly make/upscale toys from household items and pieces of toys he’s destroyed. He likes those just as much as the ones I buy. Basically, before I throw anything away, I ask “is this bird safe?” and then “how can I make a toy out of this?”
I’ve bought some foot toys, but his all-time faves are Gatorade caps, binder clips, chopsticks, and ink pens. 🤷🏻♀️
