Behavioural Monitoring and Threats Assessment of Ibisbill (Ibidorhynchastruthersii) in the Wintering Site, East Rapti River, Hetauda, Nepal

Ibisbill is a resident breeder in the Himalayas and winters in the lower Terai of Nepal. It has been nationally assessed as Endangered due to disturbance, hunting, habitat loss and climate change. We did a field survey in the East Rapti River from Late November 2022 to Mid-March 2023 to assess the population status, behaviour and threats in the Ibisbill wintering ground. Observations on the behaviour were made at three selected sites, each of 1.5 km transects. Household survey was conducted with 50 respondents using structured and semi-structured questionnaires to assess the prominent threats along with direct observations. A total of six Ibisbills were recorded during the study period in the wintering ground. Ibisbills fed on both terrestrial and aquatic invertebrates including stonefly, mayfly and caddisfly larvae. Feeding and Foraging accounted for 55% of the total activity time in winter followed by Resting (22%). During the survey, the bird was quite inactive and solitary as well as found to be good swimmers, preferring to cross rivers by swimming rather than flying. People in the vicinity of the East Rapti River reported that extraction of stones and boulders, pollution and disturbances by human activities were major threats to Ibisbill. We recommend further monitoring of the species and protection of the wintering grounds from excessive anthropogenic activities.
