Firefighters use duck calls from YouTube to lure frightened ducklings out of storm drain pipe

Firefighters later reunited the four ducklings with their mother.

Firefighters tapped their creative juices Thursday in order to rescue a flock of mighty ducklings that became trapped in a storm drain pipe in Littleton, Colorado.

"Did you play duck sounds?" One firefighter is heard asking another in the video. "That is genius."

The flock was safely reunited with their mother, according to firefighters.
