"Mini" Macaws ARE Macaws! They are small Macaws, that's it, that's the difference! Seriously, don't think for a minute that any of the species of "Mini" Macaws, whether you're talking about Hahn's, Illeger's, Severes, etc., are any different than the full-size Macaws...They are Macaws in every way, from personality to behavior to their needs, wants, vocalizations, etc. They are just simply smaller.
And as already pointed-out, all species of parrots can be extremely destructive, it just depends on the bird. As far as any species of Macaw goes (mini or full-size, doesn't matter), they are extremely intelligent and get extremely bored very quickly. So yeah, if they become bored, if they aren't getting enough affection, attention, interaction, etc. every single day, they are going to be just as destructive as any parrot can be. Some will be worse than others, some better than others. It just depends on the bird. But you should go-into the process of getting a parrot, any parrot, with the assumption that the bird you get may very well have a tendency to be destructive. And I would also go into the purchase of any species of "Mini" Macaw with the mindset that they ARE a Macaw, every bit the Macaw that a Blue and Gold, a Scarlet, a Catalina, etc. is, they are simply smaller.
