Geese are largely vegetarians and are especially fond of grasses and grains. During hunting season they'll target a variety of crops, with barley usually at the top of the list. They'll also eat rice, wheat, corn, oats, alfalfa and a sampling of grasses and other crops. Geese normally aren't early risers and typically head out to feeding areas well after the sun comes up. However, it's a good idea to be set up by shooting hours for early birds that are the exception to the rule. Geese normally will feed for two to four hours in midmorning and then fly to a roost area, which may be the bank of a river, the shore of a lake or the middle of a large reservoir. During cold weather, birds may also feed later in the afternoon.
