The Ornithologia Neerlandica – De Vogels van Nederland – is a work of five volumes. It was written by Prof. E.D. van Oort (1876-1933) and illustrated by M.A. Koekkoek (1873-1944). It was published between 1922 and 1935. The text of the final volume was completed by G.A. Brouwer (1898-1981). 

Van Oort was one of the founders of the Dutch Ornithological Society, in 1901, and has contributed much to the knowledge of birds, in particular their migratory habits. He established the practice of ringing birds in the Netherlands, thereby contributing to the knowledge of the distribution of bird species. He also published several lists of bird species that occur in the Netherlands.
