A great gift idea for your husband who likes ornithology would be a birdwatching kit. The kit could include binoculars, a guidebook, and a bird song identification app. You could also consider giving him a birdhouse kit or a nesting box.
Another thoughtful gift idea is a day trip to a local bird sanctuary or a guided birdwatching tour. You could also give him a personalized bird-themed photo album or a framed artwork featuring his favorite bird.
Lastly, you could surprise him with a membership to the National Audubon Society or a subscription to a birdwatching magazine to keep him up-to-date on the latest information and discoveries.
Or you can get him a star map with the date when he was born.
