Song & Call Comparison
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.
Keel-billed Toucan
Produces a repeated frog-like croaking 'prrrek-prrrek' or 'terrio-terrio'. Not melodic; the call resembles a mechanical rattle or frog. Also gives bill-clattering.

About These Birds

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。
Keel-billed Toucan
The keel-billed toucan is the national bird of Belize and one of the most recognizable birds in the Neotropics. Its oversized bill, which can be a third of its body length, is actually very light due to its hollow honeycomb structure. Toucans roost communally, with up to six adults squeezing into a single tree cavity.
