Size Comparison
Habitat Comparison
Eurasian Wren
Dense undergrowth in woodlands, gardens, hedgerows, and rocky areas. Prefers tangled vegetation close to the ground.
White-tailed Eagle
Coastlines, large lakes, and rivers with mature trees or cliffs for nesting. Requires large undisturbed areas.
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.
White-tailed Eagle
High-pitched, yelping 'klee-klee' and deep barking 'ra-ra-ra'. Less vocal than Bald Eagle but similar chattering quality. Gives gull-like wailing near nest in breeding season.
Geographic Range & Migration
Eurasian Wren
Eurasia from Iceland and western Europe to Japan. The only wren species found outside the Americas.
White-tailed Eagle
Northern Europe and Asia from Greenland and Scandinavia to Japan. Reintroduced to Scotland and Ireland.

About These Birds
Eurasian Wren
The Eurasian wren is one of the smallest birds in Europe but possesses an astonishingly loud song for its size. Males build multiple dome-shaped nests, from which the female selects one to line and use. In British folklore, the wren is known as the king of birds for outwitting the eagle in a flying contest.
White-tailed Eagle
The white-tailed eagle is Europe's largest eagle and the fourth-largest eagle in the world. Once extinct in Britain, it has been successfully reintroduced to Scotland and Ireland through conservation programs. These powerful raptors can live over 25 years and form lifelong pair bonds.
