Count Ettore Arrigoni degli Oddi MBOU (13 October 1867 – 16 February 1942), was an Italian ornithologist.
[2] In 1911 he founded the Rivista Italiana di Ornitologia, (RIO) a scientific journal on ornithology, together with Filippo Cavazza (1886–1953), Francesco Chigi (1881–1953), Alessandro Ghigi (1875–1970), Giacinto Martorelli (1855–1917) and Tommaso Salvadori (1835–1923).
[3] In 1898 his first article in an English journal was published: 'Notes on some specimens of Anatidae in the late Count Ninni's collection,' in The Ibis.
The scientific nomenclature was up to date and vernacular names in Italian, French, German and English are provided for each species.
There is a detailed and differential description of each species, and notes on distribution, breeding, eggs, habitat, song, and food.
