How does the northern hawk owl differ from most other owls?

The northern hawk owl (Surnia ulula) differs from most other owls primarily in its hunting habits and physical appearance. While the majority of owl species are nocturnal, the northern hawk owl is largely diurnal, meaning it hunts during the day.12

Its physical characteristics also distinguish it from many of its relatives:

• Appearance: It possesses a long tail and short, pointed wings that cause it to resemble a hawk.12
• Facial Structure: Unlike many other owls, its facial disk does not extend above the eyes, and it lacks ear tufts.1

These traits, particularly its daytime activity, set it apart from other species often referred to as "hawk owls," such as the New Guinea hawk owl or members of the Ninox genus, which are typically nocturnal or crepuscular.1
