Since the text is in German, it is best suited for readers fluent in the language.

The book's defining feature is its organization by rather than strictly by taxonomic order. This approach makes it a precursor to modern "where to watch" and habitat-based identification guides. The contents are divided into sections such as:

Species inhabiting dry meadows, fields, and agricultural areas. Wetlands: Birds of moors, swamps, and inland damp meadows.
