    Fantastic report – and what an animal! I definitely want to try for this one next time I’m in Borneo. I think you were there in December the second time – what months do you recommend?

      Thanks Jon. You definitely should, the place and langur are so good. I think December and January are best for the high water and fruiting but definitely check with Erwanto because the seasons are a bit all over the place. I think as long as the water is good you will see them at the better location – the fruit just increases the quality and frequency of the sightings I think. I’m in the process of doing a presbytis canicrus report now. I’ll upload it soon.
