I was wondering if anyone experienced and knew why I usually experience a lull in feeder use in mid to late August through early September. I have had several others mention it to me recently.

While some of it is that the highly visible Black-headed Grosbeaks start leaving, the normal chickadees, nuthatches, juncos, towhees and Song Sparrows are still around and for the most part not feeding young any longer. I get an almost complete cessation of feeder use by all of these species. Then there's a frantic stocking up by the nuthatches and chickadees later on but now it's very dead.
