According to the New York State Department of Conservation, it's best not to feed waterfowl at all. But if you absolutely must, the sign above recommends the following snacks:

• Half cut seedless grapes

• Cooked rice

• Birdseed

• Oats

• Peas

• Corn

• Chopped lettuce

And please make sure the snacks don't land in water.
