Eurasian Wren
Dense undergrowth in woodlands, gardens, hedgerows, and rocky areas. Prefers tangled vegetation close to the ground.

Eurasian Wren
Extraordinarily loud for its tiny size: a rapid, powerful stream of trills, buzzes, and churring phrases. One of Europe's loudest songs by volume relative to body weight.
Geographic Range & Migration
Belted Kingfisher
North America from Alaska and Canada to Central America and the Caribbean. Northern populations migrate south in winter.

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。
Eurasian Wren
ヨーロッパ最小クラスの鳥の一つで、体の大きさに不釣り合いな大きな声で鳴く。民話では鳥の王様とされる。
