The northern hawk-owl is a partially diurnal hunter, although it has been recorded hunting at varying times and does not appear to have a preferred hunting time. Whether the bird resides in Eurasia or North America, the strategy is usually similar. The northern hawk-owl will perch and scour the immediate area for prey. As these owls are considered a search-oriented species they likely do not stay put for long if the site is not producing prey. The hawk-owl prefers open, forest-type environments when perching. These environments include sphagnum bogs and partially deforested areas. The preferred perching tree of the northern hawk-owl is the spruce tree. When the hawk-owl attacks, it goes from a horizontal posture into a gliding dive. If the prey is further away, the bird will flap its wings a few times during the dive to increase distance. The hawk-owl has exceptional hearing and can plunge into snow to capture rodents below the surface.
