I have been using this toy for a while (maybe for over a year) for a green wing macaw who destroys (macaw) toys. So far he has not destroyed it and works hard at getting out his walnut in the shell. It's always best to desensitize your bird to new toys in their environment. When your bird is ready to use this toy for the first few times I would recommend showing them that you are putting a highly desirable treat inside, and not fully closing it/tightening it (don't make it too challenging at first you would want to set the stage for success) If they succeed at getting the treat the first few times they are more likely to repeat the behaviour. As they get better make it more challenging by tightening the wingnuts. Also, move the toy all around the cage inside and out to keep things interesting and challenging. Great toy for motivated birds who love treats, I would recommend this toy for medium to larger size birds such as African Greys, Cockatoos, and definitely macaws.
