Body length: 9-10 cm
Body mass: 6-12 g
Appearance: reddish-brown upperparts, paler belly, cocked tail.
Very widespread and in many habitats, so overall numbers high; but not very common anywhere. Occupies coniferous and broadleaved forests, but also riverbanks, gravel pits and roadsides. Parks and gardens avoided (in Poland). Builds impressive roofed nest, typically in windthrown tree, pile of branches, or nest-hole (nestbox). Male begins work that attracted female then completes. Nest material is moss, as concealed by ferns. In some regions almost half of all males are polygamous. Diet is of insects, tadpoles and small fish.
Polish wrens mostly winter in western and southern Europe, though a few remain here.
