💡 Everyday Comparisons for Size, Mass & Speed

💡 Its wingspan of 1.7 m is about the height of an adult, and its maximum mass of 1.6 kg is slightly heavier than one 1.5 L bottle of water (Comparison).
💡 Because a single owl may eat over 1,600 lemmings in 1 year, it helps regulate rodent populations (ADW, food habits and 'Economic Importance for Humans: Positive').
💡 In the Arctic region, it is also known to steal prey from traps set by fur trappers (ADW).

🦴 2. Anatomy & Morphology

Its body length is 63–73 cm and its wingspan averages 170 cm. Males weigh 1,450–1,500 g and females weigh 1,550–1,600 g, making females slightly heavier.

🔍 3. Ecology & Behavior

It hunts from high perches with a wide view, feeding mainly on lemmings and mice while also taking rabbits, seabirds, and fish when opportunities arise. A single bird may eat more than 1,600 lemmings in 1 year, and depending on food supply it lays 3–11 eggs (up to 16) per clutch.
