Six baby ducks were reunited with their mother after being trapped in a storm drain on Saturday thanks to one firefighter's quacking ringtone, The Guardian reported.
Firefighters raced to the scene in Slidell, Louisiana, after a resident reported seeing the mallard ducklings fall into a storm drain, according to the St. Tammany Fire District.
One of the firefighters, Cody Knecht, dropped down into the drain to try and coax the helpless ducks toward him while his colleagues helped from above.
"With the help of a duck-call ringtone on his iPhone, firefighter Knecht was able to lure the baby ducks to him. It took about an hour and a half to rescue four of the six baby ducks," said Chad Duffaut, the district's chief of fire prevention.
The team transported the birds to the fire station and returned to rescue the remaining two after giving them a chance to calm down, Duffaut said.
All ducklings were safely reunited with their mother in the canal behind a home near the storm drain.
The heartwarming rescue comes a week after the district rescued a duck that got trapped in a chimney.
"If you don't know who to call for help, call us," Fire Chief Chris Kaufmann said.
