High up in the trees of Green Lawn, Josh has made an amazing discovery! He found a real falcons nest hidden among the branches, complete with tiny, chirping baby birds. He loves visiting the spot every single day to quietly watch the wild animals grow. He is incredibly excited to share his secret nature spot with his best friends, Dink and Ruth Rose. When Josh brings his friends to the woods to show off the amazing sight, they are met with a terrible surprise. The nest is completely empty! The baby falcons have vanished without a trace, and the kids know that wild birds cannot simply fly away on their own at such a young age. Someone must have taken them in the middle of the night! The three detectives immediately launch a rescue mission to find the missing animals. Follow along as they search the forest floor for clues, examine scattered feathers, and try to track down the sneaky bird thief. You will need sharp eyes to help them spot the evidence hidden in the woods. Can the friends return the babies to their home?
