Size Comparison
Habitat Comparison
Eurasian Wren
Dense undergrowth in woodlands, gardens, hedgerows, and rocky areas. Prefers tangled vegetation close to the ground.
Great Blue Heron
Wetlands of all types including marshes, swamps, riverbanks, lake edges, and coastal shores. Also hunts in fields and meadows.
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.
Great Blue Heron
Deep, harsh, croaking 'frahnk-frahnk' call in flight. Also gives low guttural grunts at the nest. Alarmed birds give repeated croaks. Mostly silent for such a large wader.
Geographic Range & Migration
Eurasian Wren
Eurasia from Iceland and western Europe to Japan. The only wren species found outside the Americas.
Great Blue Heron
North and Central America from Alaska and southern Canada to the Caribbean and Galapagos Islands.

About These Birds
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。
