Observation of mixed-species vulture assemblages in the Khoh River floodplain of western Uttar Pradesh, India

Abstract
Ad hoc field surveys were conducted on 11 and 12 March 2025 along the Khoh River floodplain in the Najibabad Forest Division, India. On two occasions, the near-threatened Cinereous Vulture (Aegypius monachus) and Himalayan Vulture (Gyps himalayensis) were observed co-occurring with the endangered Egyptian Vulture (Neophron percnopterus ginginianus) at carcass-feeding sites. Up to 14 individuals were recorded in mixed-species assemblages. These observations document the co-occurrence of the three species and describe basic feeding behaviour, including differences in spatial positioning and interactions at carcass sites. Given the limited temporal scope of the study and the absence of quantitative behavioural analysis, the findings are presented as observational records. Further systematic studies are required to better understand behavioural patterns and ecological interactions in this region.
