Size Comparison
Habitat Comparison
Eurasian Wren
Dense undergrowth in woodlands, gardens, hedgerows, and rocky areas. Prefers tangled vegetation close to the ground.
Great Cormorant
Coasts, estuaries, lakes, rivers, and reservoirs. Nests in colonies in trees, on cliffs, or on the ground.
Song & Call Comparison

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 Cormorant
Deep, guttural grunts and 'karrr' calls at colonies. Bill-clicking and hissing in threat displays. Silent at sea. Colonial noise can be deafening during the breeding season.
Geographic Range & Migration

Eurasia from Iceland and western Europe to Japan. The only wren species found outside the Americas.
Great Cormorant
Very wide range across Europe, Asia, Africa, and Australasia. One of the most widespread cormorant species.

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。
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
