These last couple of days have been very cold – and very bright and sunny – with effective temperatures, factoring in wind-chill, of -32degC at the moment.

Yesterday, driving a minor road across flat fields on Montreal island the car was surrounded by a "blizzard" of Snow Buntings glinting in the sunshine ….. just a delight. Then coming to work this morning there was a small pool of not-quite-yet frozen water on the river with a huddle of dormant ducks all back-lit by the low, red rising sun, and of course the camera was at home.

Days like this can kill you with the cold but I wouldn't be anywhere else on earth at the moment.
