Strigiformes are divided into two main families:
- Tytonidae (Barn Owls): Known for their heart-shaped facial discs, these owls have exceptional low-light vision and a unique, eerie screech instead of a typical hoot.
- Strigidae (True Owls): This family includes most owl species, characterized by round facial discs, diverse vocalizations, and robust bodies adapted for silent flight.
Tytonidae and Strigidae.
Barn owls have a distinctive heart-shaped facial disc.
Most owl species belong to the family Strigidae.
Silent flight, exceptional hearing, and nocturnal vision are key adaptations of Strigiformes.
Examples of Barn Owls: Tytonidae
Barn owls have a distinctive heart-shaped facial disc.
Barn owls (Tytonidae) are known for their distinctive heart-shaped facial discs, which aid in sound localization. They typically have pale, golden, or white plumage and are found worldwide except in polar regions and some islands. Their acute hearing and silent flight make them efficient nocturnal hunters, primarily preying on small mammals.
- Heart-shaped facial disc for sound localization
- Pale, golden, or white plumage
- Cosmopolitan distribution, excluding polar regions
- Exceptional hearing and silent flight
- Primarily hunt small mammals at night
Barn owls mainly avoid polar regions and some isolated islands.
Barn owls primarily eat small mammals.
The genus Tyto includes many barn owl species.
Barn owls have a heart-shaped facial disc, exceptional low-light vision, and a worldwide distribution excluding polar regions.
Examples of True Owls: Strigidae
True owls have round facial discs, diverse vocalizations, and robust bodies.
True owls (Strigidae) possess round facial discs that help funnel sound to their ears, enabling precise hearing. They exhibit a wide range of sizes and colors, from the tiny elf owl to the imposing eagle owl. Their silent flight, strong talons, and sharp beaks make them effective predators, hunting anything from insects to small mammals. This family boasts remarkable vocal diversity, including hoots, screeches, and whistles.
- Round facial discs for sound direction
- Wide size and color variation
- Silent flight and powerful talons
- Vocalizations include hoots, screeches, and whistles
- Prey includes insects, rodents, and other small animals
Great horned and snowy owls are members of the Strigidae family.
True owls have round facial discs.
Strigidae have round facial discs and more diverse vocalizations compared to Tytonidae.
True owls (Strigidae) have a highly developed sense of hearing.
Strigidae have round facial discs, silent flight, and a wide range of vocalizations.
Conclusion
Strigiformes, the order encompassing all owls, are split into two distinctive families: Tytonidae (barn owls), renowned for their heart-shaped facial discs and exceptional low-light hunting abilities, and Strigidae (true owls), characterized by round facial discs, diverse vocalizations, and a broad range of species from tiny to formidable. Both families share remarkable adaptations like silent flight and acute hearing that make them master nocturnal predators.
- Strigiformes includes Tytonidae (barn owls) and Strigidae (true owls).
- Barn owls have heart-shaped facial discs and a global distribution, except polar regions.
- True owls feature round facial discs, diverse species, and vocalizations ranging from hoots to screeches.
