About These Birds
European Roller
ヨーロッパで最も色彩豊かな鳥の一つで、求愛時にローリングと呼ばれる独特の空中飛翔を行う。
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.
