#올빼미#Strix nivicolum

📖 1. Overview

The Himalayan Owl is a medium-sized owl with a round face and no ear tufts, and in Korea it is an uncommon tree-dwelling resident bird. Because Strix nivicolum was split from the European Strix aluco, many sources still list it under the older name.

🦴 2. Anatomy & Morphology

Its head is large and round without ear tufts, and its dark eyes face forward. Its ears are placed asymmetrically on the left and right, allowing it to pinpoint the direction of sounds.

🔍 3. Ecology & Behavior

It feeds mainly on rodents such as wood mice along with amphibians, birds, and beetles, and eats more birds in cities. It uses tree hollows, old nests of other birds, buildings, or nest boxes, laying usually 2–3 eggs.

🇰🇷 4. Connection to Korea

In Korea, it was designated as a Natural Monument (Korea) on November 16, 1982, and is an uncommon resident bird that sits motionless on tree branches by day and becomes active at night.
