I think the weather probably has something to do with birds not being at feeders, but there seems to be a disturbing lack of some species anywhere locally, not just at feeders. I did three Christmas Bird Counts and could not find a single Tufted Titmouse. Other participants found a few of them, but the totals for all three were way low. Chickadees and crows were difficult to find too. One idea that people are tossing around is that the excessively wet summer resulted in more mosquitos, resulting in higher levels of West Nile disease. Whether that's the right explanation I don't know, but it seems like a reasonable theory.
