This is a not so common bird here, I have seen this only two or three times. These photos were taken last time when I saw the bird, in February.
About to hop...
Warblers are usually very difficult to distinguish between. Thanks to Mr. Praveen (Keralabirder Yahoo Group) who who suggested that this looked like a Blyth's Reed Warbler.
The bird belongs to the family Acrocephalidae and species is Acrocephalus dumetorum.
Please watch this slideshow which is compiled from my best bird photos.
Hope you liked.
