Caretaker Marta Silva, right, and biologist Judith Cardenas look at a baby night monkey at a wildlife shelter in Bogota, Colombia, Thursday, Feb. 21, 2013. Silva works with the neonatal unit of Bogota's Wildlife Reception Center, part of the capital's environment ministry, where she has nurtured species ranging from birds to turtles to primates. Now she is looking after the night monkey of the genus Aotus that lives in the tropical forests of South America, including Colombia, Brazil and Ecuador. (AP Photo/Fernando Vergara)
