In 1773 Caetano Monti's paper “Sur l'oiseau qui porte à Bologne le nom de Pendulino, et en Pologne celui de remiz” was reprinted in Paris. It played a decisive role in the scientific description of Penduline Tit and it's nest, and provided the first significant information relativing to the biology of this species. Monti was also the first to correct number of inaccuracies in earlier zoological treatises considered as “classics”. His own work was recognized throughout Europe, and quoted by German and French naturalists as Buffon. Linnaeus referred to it in his own description. Monti's analysis also enables us to gain precious information concerning the way in which ornithologists worked at the time, and the methods they used: analysing classical writings, “interviewing” bird catchers and peasants, information from missionaries, field work, analysis of specimens from zoological collections, and preparing descriptions and iconographies.
