Day was breaking when the marten caught a faint but familiar scent of squirrel and followed its nose to a old fallen red fir.
That's where it discovered the camera trap that periodically flashed in the dim light.
But the camera didn't detract it from its goal.
It soon discovered that the squirrel was deep beneath a huge splinter of sap wood.
It squeezed down into the gap and seized the prize.
A week later a large male marten crossed the log.
Perhaps the scent of squirrel and marten still lingered.
