One idea could be to get your son a beautiful bird watching book filled with stunning photographs and information about different species of birds. You could also take your son to visit a bird sanctuary or an aviary, where he can learn about birds in a natural setting. If you want to get more personal, you could even consider getting your son a bird feeder that he can hang outside his window so that he can observe and interact with local birds on a daily basis.
Or you can get him a star map with the date when he was born.
