Sullivan said the goose overpopulation has inundated the city, leaving messy droppings, over-grazing plants, damaging the habitat and polluting the water.
He said the geese were captured and a waterfowl processor humanely euthanized them with carbon dioxide gas before providing the meat to food shelters.
Sullivan said he believes this is the first time the city has turned to killing the geese in almost 15 years of population monitoring. In the past, officials used a slower method of poking holes in eggs.
Maryland natural resources police are investigating the deaths of seven bald eagles and a great horned owl in a pair of incidents on the Eastern Shore that officials believe can be traced to the intentional poisoning of foxes, raccoons and other animals.
