Song & Call Comparison
Barn Owl
An eerie, drawn-out rasping shriek 'shreeeeee' — not a hoot. Also gives hissing, snoring, and bill-snapping when disturbed. Chicks call with a persistent rasping hunger call.
Japanese White-eye
Sweet, high-pitched 'tsee-tsee-tsee' whistle and soft melodic warbling. Flocks produce a continuous tinkling chorus. Alarm is a sharper 'tset'. Song is gentle and rhythmic.

About These Birds
Barn Owl
メンフクロウはあらゆるフクロウの中で最も非対称な耳を持ち、動物界最高の聴覚的方向定位能力を誇る。完全な暗闇の中でも音だけで獲物を捕まえることができる。特徴的なハート形の顔は放物線状の皿として機能し、ずれた両耳に音を集める。
Japanese White-eye
The Japanese white-eye is a familiar garden bird across East Asia, beloved in Japan where it is called mejiro. These sociable birds form flocks outside the breeding season and are important pollinators of plum and cherry blossoms. Unfortunately, introduced populations in Hawaii have become invasive, competing with native honeycreepers.
