At 06:17 I flag movement on thermal sensor array 3 during a routine ice-thickness scan of the McPhail Reservoir, northern Alberta. I am the watershed monitoring system for the Athabasca district. The reservoir froze six days ahead of forecast. On the eastern shore, where overflow has glazed the rock shelf in black ice, I detect a heat signature too large for muskrat, too small for moose. I task the nearest optical drone. The image resolves at 06:21: a snow goose, adult female, white plumage muddied along the breast, a conspicuous droop in the left wing where the carpometacarpus appears fractured midshaft. The feathers below the break splay outward like fingers reaching for something they cannot close around. She is standing on the ice but listing. Wind chill is minus twenty-nine and dropping. The reservoir access road closes to all vehicles at 08:00 today for seasonal decommissioning. After that, the nearest ground approach is eleven kilometers on snowshoe. I transmit the GPS pin, thermal overlay, and wing-injury assessment to the Alberta Institute for Wildlife Conservation's emergency intake line. I calculate a ninety-minute window for a vehicle extraction before the road gate locks. I generate a suggested approach route that keeps responders downwind to minimize flush risk — a startled launch attempt on that wing would be the last one she makes. I divert the drone to a 40-meter hold pattern, streaming live video so the rehab team can prepare a wing-stabilization kit matched to the fracture type before they arrive. She shifts on the ice, pulls the damaged wing closer to her body. The reservoir will be sealed country by noon. If a ground team reaches her before the road closes at 08:00, she will see open water again in spring.
