Scops owl
By the mid-19th century, scientists knew that Otus had more than one genus in it. First, in 1848, scientists made a second genus for screech owls, Megascops. In 1850s, they made other genera for other owls that had been in Otus.  They made Macabra, Ptilopsis, Gymnasio, Gymnoglaux, and Pyrroglaux for different groups of owls.
