Elevation and landscape change drive the distribution of a montane, endemic grassland bird

This dataset documents the presence and abundance of the Nilgiri pipit (Anthus nilghiriensis) in 170 survey sites across most of its global range. Between one and four surveys were carried out at each site between November 2017 and May 2018 by experienced observers. Survey duration was proportional to site area. A wide range of habitat characteristics were also surveyed, and additional habitat characteristics for each site were gathered from remotely sensed data.Â
