The birds do group huge come late november they can be impossible to get shots. Depending on the conditions colder the better for chickens but hard to get especially in the pickup. Some years the birds will eat buffalo berries. Other times they are in grain fields. Best or most birds i have encounterd were in slope bowman really good but williams an divide has a lot. Some of those u clean an the white fat is incredible. Guess its could be an older one or just how they store up energy for the prairie winter white fat. You hsve to respect a bird that does not migrate.In the old days of crappy west side corn, we killed piles of them in armpit high corn. Alfalfa too. The tops of hills on windy days. Shady bushes on the hot days. And pass shot them into flowers too. The variety makes it fun.
