In this July 8, 2019, photo, a monkey pulls on the clothes of Saraswati Dangol as she arrives to feed monkeys in the forest near Pashupatinath temple in Kathmandu, Nepal. For the past four years, Dangol has been bringing the bread every day to feed the monkeys. As soon as they see her with her white sack, they gather around her, some patiently waiting for their turn while others less patiently snatching the bread from her hands. Many of Dangol's regulars are elderly, or are mother or baby monkeys who are unable to fight for their share of food in the wild. (Photo by Niranjan Shrestha/AP Photo)
