I had seen and photographed black howler monkeys before in Central and South America. This red howler is a sub species found only in the north western Amazon basin. I was in a canoe on Lake Chalalan and the light was fading fast when a troop of red howlers came to an area along the lake to sleep for the night. This guy was the alpha male of the troop and a couple of seconds after this shot was taken he was asleep in the V of the tree.
