From this AP story:
For a farmer, few things are more frustrating than Canada geese descending like a biblical plague of locusts upon a freshly planted field to feast on soybean or corn shoots. Grower Dave Black, who farms more than 1,200 acres of corn, wheat and soybeans along the James River southeast of Richmond, has seen "a cloud of geese" glide onto his fields by the hundreds to pick them clean. "As soon as the corn starts emerging, up to knee high," Black said of the feathered pests that flock on his fields. "They're just back and forth." For years, growers such as Black had to ask the federal government for permission to kill resident Canada geese if attempts to shoo them off didn't work. By the time they received it ˜ weeks or even months later ˜ the geese had already gobbled up crops and flown away. Now, farmers in some states no longer need the U.S. Fish and Wildlife Service's permission to use lethal means to protect their fields from geese. The change in federal rules made in 2007 affects resident geese, not the migratory variety that fly south from Canada in September, and applies to 41 states, mostly in the Atlantic, Central and Mississippi flyways. Those states now can decide whether farmers can use lethal methods to control resident Canada geese, eliminating one layer of bureaucracy.
