I don't have good records to compare year-over-year, but we have had a
consistently large flock of white-throated sparrows at our feeders in Fairfax
County (Fort Hunt area) this winter -- far more than we've had over the past
four years. At least six at a time, and often at least a dozen (their constant
motion makes getting a firm count challenging!). Perhaps in part because we
didn't get our backyard leaves raked before the rain and snow hit?
