i came across this image i took at the san diego zoo between 1983 and 1985. While wandering around I came across a canvas enclosure and peeked my lens through an opening in a corner, capturing these red shanked douc langurs. They mesmerized me, and i am so glad i captured that memory. The douc langur on the left looks pensive, perhaps apprehensive, maybe being processed in or out. Does anyone know anything about the douc langur population there in that time frame?
