Observation: Blyth's Reed sized (13-14 cm) warbler seen feeding on tall bamboo at Narendrapur, 10 kms south of Kolkata city. While feeding it constantly fanned its tail, a behaviour which initially attracted our attention to the bird. The movement of the bird was fantail like, the bird seemed to slide/glide from one feeding point to another. Bird did not call even once in 12 minutes.
Observed by: Sumit K. Sen, Bhaskar Das, Anjan and Aranya Gupta
