Eurasian Wren
Dense undergrowth in woodlands, gardens, hedgerows, and rocky areas. Prefers tangled vegetation close to the ground.
Song & Call Comparison
Common Raven
Highly varied: deep resonant 'kraa-kraa-kraa', hollow 'tok-tok', liquid 'klonk', and wing-whooshing. Among the most intelligent corvid callers; uses calls contextually in groups.

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
Common Raven
Holarctic distribution across North America, Europe, Asia, and North Africa. The most widely distributed corvid.
Eurasian Wren
Eurasia from Iceland and western Europe to Japan. The only wren species found outside the Americas.
