Baby Ducks Rescued from Storm Drain
Slidell, LA. – On Saturday, April 25, 2015 at approximately 5:24 pm, St. Tammany Fire District #1 responded to a call for baby ducks trapped in a storm drain. The incident occurred on Oak Tree Dr. in the Fairways subdivision in Slidell. A neighbor reported seeing a number of baby ducks fall into a storm drain. Upon arriving on the scene, firefighters verified that several baby Mallard ducks were trapped in the storm drain. Firefighters removed the top cover of the drain to gain access to the ducks. Firefighter Cody Knecht got down in the drain to try and capture the ducks. Captain Chuck Davis, Fire Operator Jason Theriot, and Fire Prevention Officer Billy Dekemel assisted 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.
Unable to capture the other two baby ducks, the crew went back to the fire station to give the ducks a chance to calm dawn. They returned about an hour later and rescued the two remaining baby ducks. All of the baby ducks were reunited with their mother in the canal behind the home where the incident took place.
St. Tammany Fire District #1 responds to numerous public service calls such as these each year. This is the second duck rescue call in less than a week. Firefighters are always eager to help and enjoy giving back to the community. Fire Chief Chris Kaufmann has stressed to our citizens, “If you don’t know who to call for help, call us”.
From daily The Independent in Britain:
Quacking ringtone used by firefighters to rescue baby ducks
The Louisiana fire department spent over 90 minutes coaxing the frightened ducklings out of a storm drain
Sunday 03 May 2015
A Louisiana fire department has managed to rescue six ducklings, after they used a duck call ringtone to entice them out of a storm drain.
Thanks to quick thinking by Cody Knecht, a firefighter with St Tammany Fire District, he was able to use his mobile phone to attract the ducklings towards the surface.
But even with the realistic, reassuring quacking sounds, it still took Mr Knecht around 90 minutes to catch the first four baby mallards in the south-east Louisiana community of Slidell.
Chad Duffaut, of the St Tammany Fire District, said that Mr Knecht rescued the other ducklings by allowing them to calm down for about an hour, before reuniting them all with their mother in a nearby canal behind a house where the ducklings were first seen entering the drain.
