[7] During the Arctic summer, snowy owls may tend to peak in activity during the twilight that is the darkest time available given the lack of full nightfall.
Due to meeting the needs of their nestlings, eastern screech owls frequently consume less per day during summer than they do during winter. Five owls captured in April, averaging about 160 g (5 + 3 ⁄ 4 oz) in males and 190 g (6 + 3 ⁄ 4 oz) in females, gained on average 28 g (1 oz) when captured in fall (October–December) and 13 g (1 ⁄ 2 ...
Several types of owls are crepuscular—active during the twilight hours of dawn and dusk; one example is the pygmy owl (Glaucidium). A few owls are active during the day, also; examples are the burrowing owl (Speotyto cunicularia) and the short-eared owl (Asio flammeus). Much of the owls' hunting strategy depends on stealth and surprise.

The bird family Tytonidae, which includes the barn owls Tyto and the bay owls Phodilus, is one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the ...
Beyond that, some cold-lovers say that exposure to icy temps boosts their mental health (and one 2023 study in Biology would agree; it found that participants subjected to cold-water immersion ...
More sound-based hunters such as the aforementioned species likely focus their hunting activity in more complete darkness. Also, owls with white throat patches such as the Eurasian eagle-owl are more likely to be active in low-light conditions in the hours before and after sunrise and sunset rather than the darkest times in the middle of the night.
