Thanks. From what I've been able to tell the potential impact of Avian Flu on the bird population may already be quite severe. It's already quite obvious as the last couple of trips to one area I frequent resulted in literally no sightings... and that's the first time that has happened in years. It's depressing, and I can only hope that this will pass and that the population will survive and eventually thrive in the not-too-distant future. We still have a couple of hummingbirds that come around and frequent our feeders. Other birds seem to be far more scarce.
