The Sedge Warbler, Acrocephalus schoenobaenus, is a small passerine bird found in reed beds and marshes across Europe and western Asia. It is known for its distinctive, melodious song and intricate vocal mimicry. The bird has a streaked brown back and a pale underbelly, with a prominent white supercilium. It is migratory, wintering in sub-Saharan Africa.

The Sedge Warbler (Acrocephalus schoenobaenus) is primarily native to Europe and parts of western Asia. Its geographical distribution spans from the British Isles and Scandinavia, across central and eastern Europe, extending into western Siberia and parts of the Middle East.

The Sedge Warbler typically inhabits wetlands, particularly reed beds, marshes, and areas with dense vegetation near water bodies. It favors environments with a mix of tall grasses, reeds, and shrubs that provide cover and nesting sites.

This species is adapted to a life in wetland ecosystems, where it feeds primarily on insects and small invertebrates. During the breeding season, it relies on dense reed beds for nesting, which offer protection from predators and shelter from environmental elements. The Sedge Warbler's presence is often an indicator of healthy wetland habitats.
