Some in our group reported "superlative views" of this rarity, but I was not in their vehicle. For me it was difficult to see this large owl hulking in the canopy and I never got a clear view of its head. However it was the only Tawny Fish-Owl of our trip. Some authors include this and the other Asian Fish-Owls with the Eagle-Owls in the genus Bubo. However recent genetic studies have confirmed their placement with the African Fish-Owls in the genus Ketupa characterized by floppy ear-tufts and unfeathered legs. Strickland revised Horsfield's original spelling "Ketupu" stating "It is better not to introduce barbarous names into science; but when done, they should at least have a Latin termination given them."
