Bicoloured Wren

The two-tailed wren (*Campylorhynchus griseus*) is one of the largest and most charismatic representatives of its family in South America. This hardy passerine is instantly recognizable by its elegant visual contrast: a deep grayish-brown back in stark contrast to its bright creamy-white underparts. Featuring a long, slightly curved beak and a distinctive white eyebrow that gives it a lively air, it stands out above all for its complex social behavior and powerful vocalizations, often performed in perfectly synchronized duets that resonate in savannahs and open forests. A true architect, it builds voluminous globular nests, asserting its presence as much through its well-groomed appearance as through its bold, sonorous temperament.
