Melodious Warbler vs Sedge Warbler

In short

The supercilium is the most reliable field mark: the Sedge Warbler has a prominent white supercilium that extends behind the eye, while the Melodious Warbler's is faint and does not extend as far. Both species are similar in size and structure, but their habitats and vocalizations can also help differentiate them.

Identification tips

1. Look for the supercilium: prominent and white in Sedge Warbler, faint in Melodious Warbler. 2. Check the habitat: Sedge Warbler in reeds, Melodious Warbler in open scrub. 3. Listen to the song: chattering in Sedge Warbler, melodic in Melodious Warbler. 4. Note the back: streaked in Sedge Warbler, uniform in Melodious Warbler.
