I planned going to Khau Ca to see Tonkin Snub-nosed Monkey and birds because i have a friend working there. In those days, it was very cold, misty and rainy on mountain but we got luck in one clearly day, that we saw the monkeys and took some pictures. We waited for another day later coming back to see them again but impossible. We just stayed in tent taking picture of birds around in bad weather days. I watched only 56 species of bird on this trip such as Great Barbet, Golden-throated barbet, Chestnut-collared Yuhina, Mountain Bulbul, Yellow-breasted Bunting, White-browed Laughingthrush, Velvet-fronted Nuthatch, Beautiful Nuthatch, Blue-winged and Orange-bellied Leafbirds, Asian Barred Owlet, Crimson, Fork-tailed and Black-throated Sunbirds, and other stuffs.
Tonkin Snub-nosed Monkey
This species is endemic to northern Vietnam, and very rare. It was thought to be extinct until the 1990s when a small population was discovered in Na Hang District in Tuyen Quang Province. Heavy poaching for food as well as the wildlife black-market and the destruction of habitat are the main reasons why the Tonkin Snub-nosed Monkey is considered to be one of "the World's 25 Most Endangered Primates".
There are estimated to be about 250 individuals throughout its known range, though the global population could actually be higher, due to the possible occurrence of this species in other areas where it has not yet been recorded. Khau Ca Nature Reserve, in Ha Giang Province, is containing its biggest population (discovered in 2002).
