I am not sure why "Common" is a part of this bird's name, for unless you live near the North Pole, they are anything but common (see map below). In over four decades of birding, I have only seen them twice (the previous two years here in the Western Upper Peninsula of Michigan). They migrate south of the Arctic when food gets scare in the winter or it has been a bad year for seed crops. This shot was taken in a house I rented before buying the farm. These tiny fellows were so accomodating in posing that they let me open the window and rest the Canon 100L macro lens on the window ledge, only inches from them while they gorged on seed. One of those "F8 and be there" moments that are special in life (at least for those of us that find great pleasure in viewing and feeding the avian world).
