The SPCA Christchurch Centre is drowning in ducks with a large number of four-week-old ducklings up for adoption.
Senior communications coordinator Sarah Hutchings said it is a common problem for this time of year.
"It is spring after all. We're also about to be inundated with kittens, and just a few months ago we had a range of birds available.
"Ducks do make great pets," she said.
The ducklings need to be adopted out in pairs or more.
