The U.S. Fish and Wildlife Service is proposing that states have more freedom in killing Canada geese to keep the birds' growing population in check. About 25 thousand Canada geese are on their way back to the Twin Cities for the summer. Thanks to the early spring, many have already arrived. Goose hunting is not allowed in the metro area, so the Minnesota Department of Natural Resources has to intervene to control the population. Last year more than five thousand geese were captured and either relocated out of state or processed for local food shelves. Still, urban geese are numerous and they can get on the nerves of homeowners. Tom Landwehr is the DNR's wetland wildlife program leader.
