Factors affecting the breeding success of colonially-nesting waterbirds in such conditions are poorly understood. Using Bayesian Network (BN) models, we explored the importance of colony size, extent of persisting wetlands, human influence as proximity to habitation, and variation in landscape conditions due to changing crops (season) on the breeding success of two stork species – the Asian Openbill Anastomus oscitans and the Lesser Adjutant Leptoptilos javanicus – in lowland Nepal. Hypotheses were framed a priori to understand relative influences of each variable on breeding success, and to determine if heavily-used wetlands could ameliorate effects due to colony size and human presence. The model with all four covariates had best performance for both species, underscoring that complex combinations of factors affected stork bree...

We surveyed MSFs in two forest types in and around the Important Bird Area of Chitwan National Park in Nepal, between 150 and 800 m a.s.l., to provide a first description of the composition of MSFs in this area. We also aimed to understand which species should be considered ‘nuclear species’, important to forming MSFs or leading them forward. Results In total, we collected records on 222 MSFs that included 100 species, and 6097 individuals. The MSFs were similar to worldwide patterns in being dominated by leaf-gleaning, non-terrestrial insectivores. However, the MSFs were more dominated by canopy species than usual, and did not have a clear gregarious, understory leading species. Rather drongos (Family Dicruridae) and minivets (Family Campephagidae, Genus Pericrocotus) acted as leaders, and ...
