The amount of warbler song has dropped considerably the last week or so. Where I use to hear Ovenbirds and American Redstarts they are no longer singing at all. The birds are obviously still around but have gotten quiet. A few species continue to sing a bit such as Black throated Green and Black throated Blue plus the occasional Magnolia and Yellow. The Common Yellowthroats are still somewhat vocal but even they have trailed off. Soon the end of summer and the beginning of fall will bring the mixed species flocks that are so much fun to work through.
