Bird Specimens in the Momiyama Bird Collection of the Yamashina Institute for Ornithology, Obtained by Exchange with Yoji Yanagihara

Abstract

Yoji Yanagihara (1892–1961) was a bird collector in Gifu, Japan. Yanagihara owned bird specimens which Tokutaro Momiyama (1895–1962) collected in Hachijojima. Momiyama stayed in Hachijojima from 1922 through 1925 and collected 2,049 bird specimens with his cooperator on the island until 1934. Of these, Momiyama exchanged 100 specimens with other collectors. In this study, I enumerated 16 bird specimens in the Momoyama collection housed at Yamashina Institute of Ornithology, which I consider that Momiyama obtained through exchange with Yanagihara.
