They said some people out walking their dog in Rollinsford saw a mallard frozen to the ice on the Salmon Falls River. They called the fire department.

WMUR-TV reports that the firefighters came out with a boat and a man with a cold-water suit to free the duck. It took about 40 minutes.

They said the ice was so thick they had to break it around the duck. A big ice cube was stuck to its wing.

The duck was recovering at a nearby veterinary office.
