Our results provide new evidence of the underexplored dietary ecology of François’ langurs in the fragmented limestone habitat. By documenting the foraging data from unique geographical populations using instantaneous scanning sampling methods, we qualitatively assessed the flexibility and adaptability of François’ langurs. The data revealed that the François’ langurs’ diet has a high degree of flexibility with seasonal variations, which could be advantageous for adapting to current habitat changes. In addition, the François’ langurs’ diet showed a high degree of selectivity, suggesting that their diet was highly dependent on important species in the habitat.
