The Greater White-fronted Goose is an opportunistic vegetarian, consuming both terrestrial and aquatic plants. This individual appeared to be feeding on green algae in a pond just east of the Northfield, Minnesota, golf course. Although this goose appears early in the spring in Minnesota, they linger through most of May. Thus a mid-April occurrence is not noteworthy. Thanks to Gerry H. for alerting me to the location of this bird.
