Bubo blakistoni (Blakiston's Fish Owl)

Synonyms: Ketupa blakistoni

Wikipedia Abstract

Blakiston's fish owl (Bubo blakistoni) is a fish owl, a sub-group of eagle owls who specialized in hunting riparian areas. This species is a part of the family known as typical owls (Strigidae) which contains most species of owl. Blakiston's fish owl and three related species were previously placed in the genus Ketupa; mtDNA cytochrome b sequence data is equivocal on which genus name is applied for this species. Its habitat is riparian forest, with large, old trees for nest-sites, near lakes, rivers, springs and shoals that don't freeze in winter. Henry Seebohm named this bird after the English naturalist Thomas Blakiston, who collected the original specimen in Hakodate on Hokkaidō, Japan in 1883.
