About These Birds
Eurasian Spoonbill
南ヨーロッパ・アジア・アフリカの湿地で繁殖するヘラサギ（体長80〜93cm）。純白の体と特大のヘラ状の嘴が特徴的。Platalea leucorodia（ヘラサギ）は浅い水中でヘラ型の嘴を左右に素早く振ることで小魚や甲殻類を捕まえる。日本では越冬個体が九州・沖縄等で確認されており、重要な保護対象種。Threskiornithidae科。
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.
