Beskrivelse: Schwarz Løvsangers storhovede look ses her. Sammenlignet med Brun Løvsanger er øjenbrynet bredere og svagere foran øjet, og tøjlestriben svagere. Dette medvirker til et nysgerrigt udseende, der helt afviger fra Brun løvsangers vredladne. Øjet virker tit stort i det i forvejen store hoved. Raddes´s Warbler demonstrates the large-headed, open-faced look; the impression, created by broad and somewhat diffuse supercilium in front of eye is striking different from the typical angry look of Dusky, which shows narrow and well-defined supercilium and distinct blackish loral streak. In Raddes, head-pattern is typical stronger and better defined behind the eye, opposite to Dusky´s browinsh-tinged and weaker defined behind the eye. In Dusky, pattern in front of the eye is thus better defined - an important field mark between the two otherwise rather similar looking species. Also note Radde´s pale and broad bill, hardly creating a phylloscopus-impression, but sometimes more of a small babbler!
