About These Birds

Olive Ibis

体長65cm。光沢のあるオリーブ褐色；裸出した赤い顔の皮膚；長い下向きに曲がった嘴。シエラレオネからコンゴ民主共和国にかけての赤道アフリカの密な林内に定住する。林床で無脊椎動物を採食；単独性で隠れ上手。森林喪失により準絶滅危惧。

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.
