The melodious warbler (Hippolais polyglotta) song is not as its name suggests – it is best described as a fast undulating warble. The song often includes nasal chattering phrases that sound like house sparrows. A lemon-yellow warbler singing on a sunny Spanish or French hillside will be the Melodious Warbler – slightly smaller than blackcaps, moss-green above and pale yellow below. The adult has a plain brown back and wings, and yellowish underparts. The bill is greyish with pinkish-yellow lower mandible and cutting edges. The eyes are dark brown. Legs and feet are greyish-brown to pinkish-grey. The sexes are identical. It breeds in southwest Europe and northwest Africa. It is migratory, wintering in sub-Saharan Africa.
