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.
Japanese White-eye
O olho-branco-japonês é uma pequena ave verde-oliva com anel ocular branco característico, muito popular como canário de gaiola no Japão e amplamente distribuído na Ásia.
