Spotted owlets, however, show only a slightly lower melatonin concentration at night with a slight increase in the early afternoon. Other owls such as the barn owl show little day-night variation. [ 13 ] [ 14 ] Seasonal changes in glandular activity have been associated with environmental factors such as temperature and humidity.
The incubation period lasts approximately 32 days. Spotted eagle-owlets will jump out of a nest that is off the ground at about five weeks of age and spend about ten days on the ground before they can fly. During this time, the owlets learn essential skills by mock-hunting and catching smaller prey such as insects.
Hunting occurs mostly at night, but this owl is known to be diurnal and crepuscular as well. Its daylight hunting seems to coincide with the high-activity periods of voles, its preferred prey. [15] It tends to fly only feet above the ground in open fields and grasslands until swooping down upon its prey feet-first. [10]
The two primary songs for the Western Screech Owl are the bounce and double trill. In a recent study, researchers utilizes sonographic analysis of tape-recorded vocalizations to analyze whether the songs differ in male and females and if so, how accurately could songs be classified by sex.

The erection of nest platforms for great grey owls was pioneered by Robert Nero in central Canada in the 1970s. Nesting may occur from March to May. Unlike, for example, osprey or white storks, the great grey owl does not predictably re-use nest sites over consecutive years. Four eggs are the usual clutch size. Eggs average 42.7 mm (1.68 in ...
The tawny owl holds a place in human folklore: because it is active at night and has what many humans experience as a haunting call, people have traditionally associated it with bad omens and death. Many people think that all owl species make a hooting sound, but that is an overgeneralization based on the call of this particular species.
The male powerful owl's song is an impressive low, rather mournful-sounding and far-carrying double-hoot, whoo-hooo, each note lasting a few seconds at least, broken up by a brief silence and the second note being usually higher pitched than the first.
