Common Redpolls

We saw quite a few of these little Common Redpolls yesterday on a rural homestead in the Drumheller area, while doing an annual Bird Count there. They were all puffed up thanks to the -30C temperatures. I was in agony (freezing hand) while taking half a dozen quick shots, but I had decided to try one of the small hand-warmer packs and this worked brilliantly. I have no idea how they work, but feeling that heat inside my glove was wonderful! Definitely recommend them!
