satchari national park, bangladesh

The Satchari forest is in Habiganj district of Sylhet division in Bangladesh, very close to the Indian border.We travelled in the outer vicinity of the National Park rather than entering it, simply because there were too many people visiting, on a holiday. I'm not sure that's a Gibbon at 1.50. Gibbons have shorter tails... Might be a Capped Langur, after all.
