They mainly eat small mammals and large insects, with grasshoppers, beetles, and moths making up a large portion of their diet but, they also eat katydids and scorpions. They are active at night or near dusk, using their excellent hearing and night vision to locate prey.
The birds wait on a high perch at night and swoop down on prey. They mainly eat small organisms with a strong focus on small mammals in their diet. Swengel and Swengel (1992) reviewed ten studies that found northern saw-whet owls eating almost exclusively mammals (88% to 100%), with most of the mammals being rodents (85% to 99+%).

Experiments by Roger Payne [1] have shown that owls are sensitive to the sounds made by their prey, not the heat or the smell. In fact, the sound cues are both necessary and sufficient for localization of mice from a distant ...
Arizona has 13 species of owl, including great horned owls, barn owls and screech owls. Here's where they live and what to do if you encounter one.

These owls hunt mainly from perches, dropping down onto prey. Occasionally, they also hunt by scanning through the treetops in brief flights or hover to catch prey.
