Bearded vultures build giant, elaborate nests that are passed down from generation to generation. And according to a new study, some of these scavengers have collected bits and bobs of human history over the course of centuries. Scientists picked apart 12 vulture nests preserved in Spain and discovered a museum collection’s worth of objects, including a woven sandal that could be more than 700 years old. Host Flora Lichtman talks with study author Ana Belen Marín-Arroyo, an archaeologist who studies ancient humans, about how the nests are giving us a glimpse into vulture culture as well as the lives of the people they lived beside.Guest: Dr. Ana Belen Marín-Arroyo is an archeologist and professor of prehistory at the University of Cantabria in Spain.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
