New records of West Himalayan Bush Warbler (Himalayan Grasshopper Warbler) Locustella kashmirensis are collated to present an up to date picture of the species' breeding, migratory and wintering ranges. Well-documented breeding records of WHBW have all been from alpine habitats with short scrub, grassy or herbaceous vegetation. Data presented in this article suggest that 38 out of the 51 breeding season records (13 June–27 September) are from open habitats above 3,000 m asl, such as alpine meadows in the western and central Himalaya. Notably, 18 of these 38 observations are within a 7 km aerial distance from the closest glacier, and three are within a kilometre . The absence of more observations at similar altitudes is possibly because meadows and other open habitats close to glaciers are difficult for birders to access.The observations reported here, particularly the southern-most records in both Uttar Pradesh and West Bengal, now confirm that WHBW can show long-distance migratory behaviour, much like the closely related SBWA which typically winters further east of Uttar Pradesh. The winter (i.e., non-breeding) distribution spans much of northern India and the Ganga and Brahmaputra plains. It winters as far west as Pong Lake, Himachal Pradesh and as far south-west as Gurugram, Haryana, and south of River Ganga in Aligarh, Uttar Pradesh; Prayagraj, Uttar Pradesh and as far south-east as West Bengal and Bangladesh; and as far east as eastern Assam.
