One of the most fascinating things to watch during a winter storm is the behavior of the birds. Given the number that showed up at my feeders during this storm, there must not be much natural food left around. This mob is a mix of red-winged blackbirds, cardinals, grackles, Harris sparrows, white crowned sparrows, and starlings. Judging from my usual mix, you can probably find a few house sparrows, a few house finch, some goldfinch and pine siskins, and a few juncos in the melee too.
The cardinals come in to feed regularly throughout each day, usually in groups of 5-7. In the evening and during storms, though, I've counted over 20 at a time using the feeders or waiting for their turn. If you look carefully (and probably enlarge the photo a bit), I count 22 (15 males and 7 females) in this shot.
