ABSTRACT
Annually, hundreds of Plain-pouched Hornbills, Aceros subruficollis, are seen in the Temengor Forest Reserve between the months of August and September. The Malaysian Nature Society (MNS), an environmental non-government organization (NGO), conducted a 64-day survey with assistance from volunteers to count the daily numbers of A. subrufi collis present at dawn and dusk during their mass movements over Pos Chiong. The Plain-pouched Hornbill fl ocks were observed heading north-east during the dawn surveys and south-west during the dusk surveys. The highest number of A. subrufi collis counted during the survey was 3,261 individuals whilst the lowest number was 595 individuals in a single count. This paper was presented at the 5th International Hornbill Conference jointly organised by the National Parks Board (Singapore) and the Hornbill Research Foundation (Thailand), in Singapore on 22nd–25th March
2009.
