How about a DIY bee house building kit? You can find different sizes and styles online or at a local store. Another idea would be to get him a book about bee house building techniques to help him expand his knowledge and skills in this area. You can also consider gifting him a set of high-quality bee house building materials such as wood, nesting tubes, and protective gear to help him start or improve his bee house project. Additionally, a personalized bee house signage or a bee-themed décor item could also be another great gift idea for him.
Or you can get him a star map with the date when he was born.
