As you can see, the birds were braving some pretty snowy conditions.
This Song Sparrow got into a confrontation with a white-throated sparrow, but I was not in a position to get any good pictures of it, since the white-throated sparrow was in front of it. What it did was bend down and spread its tail feathers up in the air.
It was sporadically windy today, so I got several shots of birds with their feathers blowing like this.
