Hello,
You can take a slightly different approach, and take some toys over saying your bird is bored with them. Same as having a bigger old cage you don't use anymore. Most people don't like being told they are wrong or what to do, and if you do report the bird they will know who did it. WW 3 may start, another option is you could offer to look after it, and the kids can come and visit it. It may no longer be wanted and thought of as a burden. Not everybody will give away or dispose of an unwanted pet.
