About These Birds
Common Kestrel
チョウゲンボウ（Falco tinnunculus）— ヨーロッパからアジア、アフリカに広く分布する小型のハヤブサ。ホバリングしながら地上の獲物を探す行動が特徴。
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.
