WASHINGTON – The National Park Service wants to begin using border collies to chase away Canada geese that frequent the Lincoln Memorial reflecting pool and other spots on the National Mall.

The agency said Tuesday that it is seeking public comments on a proposed plan to use the dogs to haze the large and growing geese population and chase them away to other parts of the park.

Park officials say large flocks of geese leave excessive droppings. One goose can leave behind 2 to 3 pounds of feces per day. Park officials say the goose droppings can damage pipes and filters in the reflecting pool and create a public health hazard.

Officials say border collies have a natural instinct to round up flocks of geese. They say no birds would be harmed.
