Avium praecipuarum, quarum apud Plinium et Aristotelem mentio est, brevis et succincta historia.

The first book on birds with clear descriptions of the appearance of individual birds based on the author’s own experiences and observations. Turner attempted to determine those birds named by Aristotle and Pliny; he added notes from his own observations on birds, identifying numerous northern European and English species for the first time.
