Seeing this Species


Grey- and Black-shanked Doucs are difficult to distinguish in the field. A distinguishing factor is the color of the face. Adult Grey-shanked Douc has a bright orange face while adult Black-shanked Douc has a dark blue face with cream eye rings. But infants and juveniles of Grey-shanked Douc also have dark bluish-grey face. Oops.


Song Thanh Nature Reserve, Quang Nam Province, Vietnam

Near the Laotian border is this remarkably preserved, yet little known nature reserve, the largest Vietnamese protected area in the Greater Annamites. This, coupled with the large tracts of relatively intact forest, make Song Thanh a vital haven for many endangered species such as tigers and sun bears.
