About These Birds
Bicolored Wren
The Bicolored Wren is a large, conspicuous wren found in open woodland, dry scrub, and savanna edges in northern South America, from Colombia to northeastern Brazil. It has a grey and brown bicolored pattern with a boldly striped head and a loud, musical song. It is highly social, living in family groups that cooperatively defend territories and raise young.
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.
