I appreciate your assistance in sorting out the ID of the below warblers . I claimed them as Blyth's reed warblers depending on one strong feature which is the length of PP as it looked to me shorter then what it would be on Caspian reed . Also I see not much contrast between rump and upperparts . However still I have doubt with the overall coloration as it favors Caspian reed , also the leg color and the buff breast and flanks .
So please let me know what you think .
