We examined roost selection by hornbills using telemetry data and determined its implication for seed dispersal. Roost selection was not influenced by nest/foraging sites. Wreathed Hornbill roosts were mostly close to the river. Hornbills dispersed only 10% of seeds at roosts, but dispersal distances of those seeds were longer. Link: https://doi.org/10.1111/btp.13039
