 | | In September 2002 the BOU (British Ornithologist's Union) recommended that the Olivaceous Warbler (hippolais pallida) should be splitted in two different species, bearing in mind, among other reasons, its geographical distribution. |
 | | The Melodious Warbler (hippolais polyglotta) is the most widespread hippolais warbler in Spain, showing grayish-green upperparts and wings, and lack of the typical pale wing panel of Icterine Warbler (hippolais icterina). |
 | | The most streaking features to separate these two hippolais are the shape and bill pattern, in Olivaceous very pale and yellowish seen from below, and much more longer and wide, which continues towards a forehead and crown flater than in Melodious, giving an expression of "big-nose". |
