Don't worry too much about which books are metaphoric. Even Win states that "a case can be made that [certain] topics are metaphors..." For Direct Learning on a programming language, you could choose a biography written about computer guru Bill Gates, or a book on how to build something, or a book of new terms, maybe a dictionary of some sort. Each of these can be tied in to a programming language, although not directly about the topic.
Good choice for your "other" birding book!
