How about a nice birding book with tips and tricks for photographing birds? Another idea could be a bird-watching journal so your friend can keep track of all the different bird species they spot while taking photographs. Or, you could get them a gift card to a local photography store where they can purchase equipment or accessories specifically for bird photography, such as a telephoto lens or a tripod. Another gift idea could be a framed print or canvas of one of your friend's favorite bird photographs that they have taken in the past.
Or you can get her/him a star map with an important date you share.
