Costa Mesa police are investigating the fatal shootings of four ducks in TeWinkle Park.

Police were called Monday about the shooting of a mallard, a Pekin duck and two Muscovy ducks known as Mr. Chipper and Grace, according to Debbie McGuire of the Wetlands and Wildlife Center, which is helping police with the investigation by X-raying the birds and extracting the ammunition.

A frequent visitor to the park said she last saw the ducks about 7 p.m. on Sunday, McGuire said.

Police asked for anyone with information to call investigators at 714-754-5637.
