One idea could be to get your grandpa a tracking guidebook, such as "Mammal Tracks and Sign: A Guide to North American Species," or a wildlife camera to help capture and identify animal tracks in his backyard. You could also look into local hiking or nature clubs, which often organize tracking walks or workshops. Another idea is to get him a personalized compass, which he can use while tracking animals in the wilderness. Finally, if your grandpa enjoys reading, you could get him a selection of books on the topic, such as "The Tracker's Handbook," by Len McDougall, or "Coyote's Guide to Connecting with Nature," by Jon Young.
Or you can get him a star map with the date when he was born.
