How about a birding field guide that she can use to identify birds in her area? You could also consider a birdhouse or a bird feeder for her to set up in her yard, so she can watch birds up close. Additionally, you could consider buying her a book on bird behavior or ornithology if she's interested in learning more about them. Another idea is a birdwatching trip or a private tour at a local zoo, aviary or sanctuary where she can learn more about the birds she loves.
Or you can get her a star map with an important date you share.
