One idea could be to get him a personalized wooden eagle carving with his name or a special message carved into it. You could also look into purchasing a piece of art featuring an eagle or a book about eagles (perhaps with stunning photography) to add to his collection. Another idea is to take him on a bird-watching tour specifically geared towards spotting eagles in their natural habitat. If he enjoys puzzles or games, you could also look into getting him a 3D eagle puzzle that he can put together and display.
Or you can get him a star map with the date when he was born.
