This superorder is represented by the sole order Strigiformes comprising the following families:

• Strigidae (Typical Owls)
• Tytonidae (Barn Owls)

Family-level timetree of the family-level relationships within extant Strigiformes based on Kuhl et al. (2021), with the distribution of each taxon being indicated by the colour-code used throughout this website (see Distribution code).
