Where to see them
Did you know…
For all its tiny size, it has one of the loudest songs relative to body weight of any European bird.
From Eurasian Wren
It is polygamous: the male may mate with several females, which is why clutch size varies so much from one nest to another.
From Eurasian Wren
It is the only representative of its family in the Old World; the other wrens, as many as 93 species, are American.
From Eurasian Wren
Its family is a recent discovery: well into the twenty-first century its species were still scattered among the bulbuls, warblers and other families, and only genetics revealed that they form a group of their own, confined to Madagascar and descended from a single colonisation.
It is an example of island adaptive radiation: from a common ancestor, the species of that family today occupy niches as different as the understorey, the canopy and the tree trunks, with very different bills.
It is a regular member of the mixed flocks of the Malagasy forest, in which several species travel together and benefit from the collective watch.
