Paul Smith, 56, of St. Petersburg, said he woke up Tuesday morning to the sound of quacking and he discovered a duck bill protruding from a dryer vent, the St. Petersburg (Fla.) Times reported Wednesday.
Smith said the duck apparently flew up to his roof and became trapped after crawling into the vent.
"Its head was just bobbing up and down," Smith said. "I didn't know whether they could bite or not. I wasn't going to stick my hand up there."
Smith called St. Petersburg Fire Rescue and firefighters arrived with tin snips to cut through the vent and free the water fowl.
Firefighters said the duck was not injured and was last seen waddling toward the nearby Crescent Lake.
