The ball turned out to be a nest, but they couldn’t tell if it was occupied.
“They [the family] didn’t know where the nest had come from, so they couldn’t return it where it should have been,” Sarah Nunn, trustee at Folly Wildlife Rescue, a wildlife rescue center in England, told The Dodo. “It was completely unopened. They had no idea if there was anything in it all.”
So they brought it to to Folly Wildlife Rescue, where Nunn was volunteering as a receptionist.
“We knew something had actually used it for nesting because it was lined with so many feathers,” Nunn said. “We very guiltily had to destroy the nest to see what was inside.”
