Chimpanzees reveal 69 socially learned behaviors, nearly doubling known cultural repertoire

For over two years, the research team followed 28 wild chimpanzees of all ages, from infants to older adults, at the Budongo Conservation Field Station in Uganda. From morning to late afternoon, they observed the daily lives of the apes in detail, recording the behavior of focal individuals as well as others within five meters. This allowed them to track what and whom chimpanzees observed closely.
