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.
Roseate Spoonbill
Low, grunting and guttural croaking sounds at nesting colonies. Generally quiet. Alarm calls are softer croaks. Vocalizations lack melodic quality; purely functional colony sounds.

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。
Roseate Spoonbill
The roseate spoonbill is the only spoonbill species in the Americas and one of the most striking wading birds in the Western Hemisphere. Like flamingos, their pink color comes from carotenoid pigments in their crustacean prey. Nearly hunted to extinction for their plumes in the 19th century, they have recovered substantially.
