Alternatively, you could get him a book on ornithology or a birdwatching guide to help him identify different species of birds. Another option is to get him a bird-themed t-shirt or a piece of artwork that features birds. Additionally, you could consider gifting him a bird-watching trip or a visit to a bird sanctuary, which could be a fun and memorable experience for him.
Or you can get him a star map with an important date you share.
