Song & Call Comparison
ハクトウワシ
High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.
European Bee-eater
A liquid, melodic 'pruik-pruik' or rolling 'prruup-pruup' in flight. Flocks give a distinctive far-carrying bubbling call audible before birds are seen. Considered a pleasant sound.

North America from Alaska and Canada through the contiguous United States to northern Mexico.
European Bee-eater
Southern Europe, North Africa, and western Asia. Winters in tropical Africa. A long-distance migrant.
