One idea could be to get him a high-quality birdwatching guidebook that he can use on his birdwatching excursions. Another idea could be to get him a birdhouse or bird feeder to attract different species of birds to your backyard or garden. You could also consider getting him a pair of binoculars or a camera with a powerful zoom lens to help him get a closer look at the birds he spots. Additionally, you could book a guided birdwatching tour in a nearby nature reserve or park for him and a few of his friends.
Or you can get him a star map with the date when he was born.
