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。
Southern Cassowary
The southern cassowary is often called the most dangerous bird in the world due to its powerful legs and dagger-like inner claw that can reach 12 cm in length. Despite this reputation, cassowaries are vital rainforest keystone species, dispersing seeds of plants that no other animal can. The purpose of their distinctive casque remains debated.
