Every 12 months, the National Audubon Society runs Christmas fowl counts: citizen-science occasions that happen all through the North American continent. Each is a 24-hour effort on one chosen day from Dec. 14 to Jan. 5.

The two counts that I manage are for the Sturgeon Bay circle and the Southern Door circle, which known as the Brussels rely. The particular rely space is a 15-mile-diameter circle.
