Popis:	As a consequence of naval duties the author spent the period from May 22, 1945, to October 12, 1945, on the island of Okinawa, situated about midway in the Ryukyu chain between Formosa and Japan proper. Publications in English pertaining to the ornithology of western Pacific islands have been few, and for many islands such as Okinawa, they are practically non-existent. Therefore this list of the birds observed there by the author together with notes made on each species is presented; all occurrences reported are based on sight observations, which usually were made with the aid of 8 X 30 binoculars.
