From this story in the Minneapolis Star-Tribune:
It's official: Minnesota will have a sandhill crane hunting season this fall for the first time in 94 years. The season will run from Sept. 4 to Oct. 10 and only in the northwest goose zone, which includes parts of about six counties in far northwestern Minnesota. The daily bag limit will be two birds, with a four-bird possession limit. Nontoxic shot will be required. Why a crane hunting season? Ten other states in the flyway already allow crane hunting, some since 1960, and Minnesota was one of the few holdouts. The midcontinent crane population, averaging over 450,000 birds, has been healthy and above goals. "It's an additional hunting opportunity we can provide," said Bill Penning of the Department of Natural Resources. That midcontinent population migrates through the northwest part of the state, which is why hunting will only be allowed there. The eastern crane population, a separate subspecies common elsewhere in Minnesota, isn't as numerous and will remain protected.
