"... A bearded vulture nest can host the animals for multiple centuries. Objects made by humans, including paper litter and plastic bags often find their way into the nesting components. And after surveying multiple sites in Spain, researchers determined that some of these accumulated artifacts are almost 700 years old. These included weaponry like a crossbow bolt and wooden lance, decorated sheep leather, and parts of a slingshot."
