Contains 93 illustrations of birds.
The online NGMCP entry says "This manuscript consists of drawings only. The drawings are of a fine quality and show many different kinds of birds. Some are depicted in couples, presumably the male and the female variety. In some cases (probably) names are also given and in places short comments (which are incomprehensible). The book (that is the format) makes the impression of being intended primarily as a scholarly work on birds rather than a piece of art. "
