About These Birds
Belted Kingfisher
ミヤマカワセミは雌の方が雄よりも派手な色彩を持つという点でユニークで、赤褐色の腹帯が余分に加わっている。これらの騒々しい鳥は独特のガラガラとした鳴き声で縄張りを宣言する。重厚な嘴を使って河岸に最大2.4mもの深さの営巣穴を掘る。
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.
