Top Highlights

  • using numerous derived features including the presence of an ossified extensorial arcus (retinaculum extensorii) on the proximodorsal surface of the tarsometatarsus
  • oldest evidence for daytime behavior in owls
  • a potential Miocene origin of nonnocturnal habits
  • demonstrates higher posterior probabilities of diurnal behavior among early diverging Surniini, and the addition of this extinct taxon into analyses enhances the hypothesis of this clade’s diurnal origin
  • recent phylogenomic analyses support the hypothesis of the independent acquisition of predatory behaviors and diets along with their nocturnal habits
