night owl

What it means

A night owl is someone who prefers to be awake and productive late into the night, often struggling with early mornings. The phrase is the natural opposite of 'early bird' and is commonly used about students, writers, gamers, and shift workers whose energy peaks after dark.

Examples

• I'm a night owl — I do my best writing after midnight.
• Night owls usually hate the standard nine-to-five schedule.
• He's such a night owl that he sleeps through every morning class.
• Being a night owl runs in the family on my dad's side.

Where it comes from

Owls are nocturnal hunters, so calling a person a 'night owl' draws an obvious comparison to the bird's late-hours behavior. The figurative use is recorded in English from the late 1500s, originally describing people who roamed the streets at night.
