Sedge Warbler

Buff-brown upperparts heavily streaked with blackish brown; distinctive broad creamy-white supercilium above a dark eye-stripe; warm buff underparts with a whiter throat and faint breast streaking. Sexes are similar.

Prominent creamy-white supercilium, heavily streaked dark brown and buff back, and warm buff-yellowish underparts.

Length: 11.5–13 cm; Wingspan: 17–21 cm; Weight: 10–14 g

A rich, chattering, variable song consisting of harsh notes, sweet whistles, and mimicry of other birds. Call is a dry 'churr'.

Insects, spiders, and other small invertebrates; during autumn migration, they heavily consume aphids and berries to build fat reserves.

Wetlands, marshes, reedbeds, damp scrub, and areas with tall vegetation near rivers, lakes, or drainage ditches.

Long-distance migrant; crosses the Sahara Desert twice a year between European breeding grounds and African wintering quarters.

Builds a deep cup nest of grass and plant stems low down in dense vegetation or bushes; clutch size is 4–6 eggs; bred from May to July.

Eurasian Reed Warbler, which lacks the prominent creamy-white supercilium and has a more uniform brownish upperpart coloration.

Acts as an insect population controller in wetland ecosystems and serves as an important bioindicator of wetland habitat health.

Least Concern (IUCN), with stable global population trends.

Look and listen for males singing from prominent perches in reedbeds or bushes near water, especially during early morning in spring.

Sedge warblers use the complexity of their song—which includes mimicking the calls of other African and European birds—as a key factor in female mate choice.
