Photo by Christian Ziegler @christianziegler | An endangered Gee’s golden langur (Trachypithecus geei) licks clay from her fingers in the Himalayan foothills. In 2017 and 2018, I spent months in Bhutan tracking and photographing these beautiful primates. I found they regularly visited an exposed clay cliff where they would eat handfuls of mineral-rich clay, which likely helps them to digest leaves and unripe fruits. The Gee’s golden langur is safe in Bhutan, but fewer than 6,500 individuals remain in the wild and it’s locally extinct across parts of its historic range. In collaboration with @uwicer, the Ugyen Wangchuk Institute for Conservation and Environment Research, Bhutan. @insidenatgeo supported me with a grant for this work. @thephotosociety #Bhutan #Conservation #RoyalManasNationalPark #Himalaya Follow me @christianziegler for more wildlife and nature stories.
