Common Nighthawk
At the tail-end of the Common Nighthawk migration, birders in Wisconsin can still catch these birds through mid-October, though with waning numbers. The true peak nighthawk season is late August in Wisconsin, depicted in the eBird abundance animation which you can see below, dated August 31.
