If you stand in the centre of the Tintamarre National Wildlife Reserve in New Brunswick near the Nova Scotia border, you get no hint of the art that surrounds you. But birds can see it: acres of sprawling circles, wandering waves, and crisscrossing chevrons, all carved into the wetlands. On Google Maps, the work looks like a child's drawings, or alien crop circles. "It probably looks very bizarre from the air," said Garry Donaldson of Environment Canada. "But guaranteed no aliens were involved in those."
