KATHMANDU, June 10: It has been four decades since Hari Krishna Shrestha, 56, has been feeding and taking care of animals at the central zoo in Jawalakhel. This is the only zoo in the country and is home to dozens of species of mammals, fish, reptiles and birds.  His long association with the precious creatures means he can read their faces. The ongoing lockdown amid the coronavirus threat has affected the species in the zoo; their behavior shows that they are missing humans, said Hari Krishna. He was busy feeding monkeys on Saturday evening.
