The Eurasian wren is a very small insectivorous bird, 9–10 cm long with a wingspan of 13–17 cm and weighing about 10 g, and the only member of the wren family found in the Old World, in Eurasia and Africa (Maghreb). It is a plump, sturdy bird with rounded wings and a very short tail, usually held cocked up, a short neck and a relatively long thin bill; it is russet brown above, paler buff-brown below, overall finely barred darker, with a cream-buff eyebrow. Young birds are less distinctly barred and have mottled underparts (Wikipedia, general species account).
It is migratory in the northern, particularly north-eastern, parts of its range and sedentary in the west and south, and is highly polygynous, an unusual mating system for passerines. The commonest call is a sharp, repeated tic-tic-tic, like a robin's but faster. A clutch of five or six eggs (range three to eleven) is laid from April. The cached account does not describe its Indian range. SoIB 2023 rates it a Low conservation priority, a resident and altitudinal migrant with a Moderate range of about 110,000 km² and an inconclusive current trend (Wikipedia, general species account; SoIB 2023).
