A collection of bird study specimens comprising 213 individuals of 106 species was donated to Yamashina Institute of Ornithology by the Fukushi family in June 2013. According to the labels, these specimens were collected in mainly Sapporo, Hokkaido, from 1879 to 1906 by Naritoyo Fukushi. Fukushi collected birds in Hokkaido with Thomas W. Blakiston, who first noticed the faunal boundary in Tsugaru Strait, which was subsequently named “Blakiston’s Line” in his honor.
