About These Birds
Common Kingfisher
カワセミ（Alcedo atthis）— ユーラシアおよびアフリカに広く分布する鮮やかな青橙色の鳥。川や池のほとりで魚を捕食する。
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.
