Owls cannot swivel their eyes, so their peripheral (side) vision is not good, and they cannot see behind them, except when they turn their head.
To compensate for their limited eye movement, owls move their whole head around to see behind them.
However, owls do not turn their head around full circle (360 degrees). What do they do instead?

Which animal has asymmetrical ears?
Asymmetrical means that two things, or two halves of the same thing, do not look the same – either the same size or the same shape. They look lopsided.
Many owls (but not all owls) have asymmetrical ears. The British Trust for Ornithology says that, in many owls, the left ear is positioned lower than the right ear. The two ears are also out of line on the vertical plane.

In Southern California, urban developers built over the burrows of the local Western Burrowing Owls, destroying their habitats.
The Burrowing Owl (Athene cunicularia) is a small, long-legged bird in the Strigidae family of owls. It measures 19-28 centimetres (7-11 inches) tall, with a wingspan of 50-61 centimetres (20-24 inches). It is native to North America and South America. It prefers grasslands, rangelands, agricultural areas, deserts and other open dry areas.
Unlike most nocturnal (night) owls, the Burrowing Owl is diurnal, active during the day.
It nests in burrows underground that a prairie dog or a squirrel has dug into the soil. It also nests in other shallow, underground structures.
The San Diego Zoo Wildlife Alliance collaborated with the United States Fish and Wildlife Service to relocate the Burrowing Owls that had lost their homes when humans began building in the area.

The Northern Great Horned Owl (Bubo virginianus subarcticus) is a nocturnal bird of prey and a raptor. It is also known as the Tiger Owl, the Hoot Owl, or the Subarctic Great Horned Owl. It is closely related to the Eurasian Eagle-Owl (Bubo bubo). It is not horned – the ‘horns’ are really tufts of feathers, called plumicorns.
The Northern Great Horned Owl is well camouflaged at night with mottled brown-grey and white feathers. Some have more white feathers than grey feathers. It does not have the reddish colour of other sub-species of Great Horned Owls. It is heavily built with a large head, a grey facial disc, and tufted ears. It has large yellow eyes. It has feathered feet with sharp talons (claws). Its beak is dark-coloured.
It can rotate its head, which gives it an arc of vision of 270 degrees. A human has an arc of vision of 120 degrees.

The lark – a small diurnal songbird – rises early and is active during the day, whereas the owl – a large nocturnal bird – is active at night.
Psychology Today has documented a recent study on chronotypes – whether a person is a morning person (up with the lark) or a late night person (to bed with the owl) and who they attract as partners.
Many studies have been previously conducted on personality traits, but there has been limited studies on chronotypes. Chronotypical behaviour is a preference for rising early or going to bed late. Morning people are called larks (and they reach peak performance early in the day) and late night people are called owls (who perform well in the afternoon or evening).
However, there is a continuum, with most people clustering around the middle – a neutral chronotype.
