This is a good example of the species' typical nfc. I recorded a few less clear examples from the same location in the previous week. While well in advance of the main southbound wave, SWTH nfc is a regular but uncommon occurrence in late July and early August in Tompkins County, NY. It is a mystery to me whether these are early migrants from some relatively proximal or distant region to the north, or individuals isolated from the main breeding range that have summered locally and are in local flight.
