How about gifting your friend a bird photography book, like "The Bird Photography Field Guide" by David Tipling or "Birds of North America" by Kenn Kaufman? Another option could be to gift your friend a bird watching trip or workshop to enhance their photography skills. You could also consider purchasing bird-themed home decor, like throw pillows or wall art, or a bird feeder to attract more feathered subjects to their backyard. Finally, you could commission an artist to create a personalized piece of bird artwork from one of your friend's own bird photographs, which would make for a truly unique gift.
Or you can get her/him a star map with the date of the wedding.
