About These Birds

Spot-breasted Ibis

体長47〜53cm。白い斑点の胸を持つ褐色；裸出した赤橙色の顔の皮膚。シエラレオネからウガンダにかけての西・中央アフリカの低地熱帯雨林に定住する。秘密主義の森林トキ；林床で無脊椎動物と小型脊椎動物を食べる。森林破壊により準絶滅危惧。

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.
