Size Comparison
Habitat Comparison
Eurasian Wren
Dense undergrowth in woodlands, gardens, hedgerows, and rocky areas. Prefers tangled vegetation close to the ground.
Gavião-real
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
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.
Gavião-real
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Geographic Range & Migration
Eurasian Wren
Eurasia from Iceland and western Europe to Japan. The only wren species found outside the Americas.
Gavião-real
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

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.
Gavião-real
The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
