You could also consider purchasing a unique birdhouse design, or a book on advanced birdhouse building techniques. Another option could be to take him on a DIY birdhouse building class in your area. This would offer a fun and interactive way to spend time together while exploring his passion. Lastly, you could consider surprising him with a custom-built birdhouse designed just for him.
