During last few days I spotted a number of reed-warblers at Borit Lake (36°26'7" N 74°51'40" E), in northern Pakistan. A majority of these Acrocephalus Warbler appear to be Blyth's Reed Warbler (Acrocephalus dumetorum), but I can see some variation among the individuals. Here I want to post a number of images to confirm the identification. This first set of 5 images show smaller birds which are surely Blyth's, but I may be wrong.
