Owls are divided into two families: the true owls or typical owls, Strigidae; and the barn-owls, Tytonidae.

The stilt-owls (Grallistrix) are a genus of true owls which contains four species, all of which lived on the Hawaiian Islands but are now extinct.

The fossil record of the barn-owls goes back to the Eocene, with the family eventually losing ground to the true owls after the radiation of rodents and owls during the Neogene epoch.

While there are clear differences in osteology between true owls and barn-owls, there has been parallel evolution to some degree and thus isolated fossil bones cannot necessarily be assigned to either family without thorough study.

Molecular analysis indicates the genus is an early offshoot from the ancestors of the rest of the true owls, and are maybe best-classified in a subfamily Ninoxinae with the genera Sceloglaux and Uroglaux.

Pulsatrix is a genus of owl in the family Strigidae.

This species belongs to the typical owls family, Strigidae.
