Kosok's bird, a 60 metre partial effigy of a giant bird carved into the Pampa, discovered by American anthropologist Paul Kosok in 1941. It is one of many geometric ground drawings comprising of lines and spirals created by the pre-Inca Nazca culture in Southern Peru between 200 BCE and 600 CE. These giant geoglyphs, etched into the Pampa de Nazca, are now a UNESCO World Heritage Site.
