How about getting them a birdhouse? It's a unique and personal gift that will enhance their love of birds. You can find a handmade birdhouse made of natural materials that looks beautiful in their garden, or a unique design that reflects their personality. Additionally, you could include a bird feeder so they can keep the birds happy and fed. Another idea is a book about different species of birds or a personalized bird-themed artwork. These options show how much you care about your friend's interests, and they will cherish this gift for years to come.
