heat seeking

if you were to travel over neroche, or indeed any landscape, with a heat seeking camera from above, as if you were a satelite with a very strong magnification range, what would all the life forms look like in the night, what patterns would they make?

human shapes asleep in their beds, birds in nests and hedges, animals in burrows curled round or waiting in the dark, all with a beating heart. what would it look like, all that red warmth emitting.

all the beating hearts, some a flutter, some knocking almost. fur and feathers, and skin, red glowing, making warmth that never burns or boils only heats.
