I was sitting in my tree stand on Saturday, October 3, 2020 in Potter County Pennsylvania (center northern county), West Branch Township. I was about 16' up in the tree. Elevation about 1700 ft.
This is an area of mostly PA northern deciduous hardwood forest although I was next to some old plantations of mature conifers (Red Pine and Norway Spruce). There were grass farm fields nearby, about 200 yards away.
A pair of small black birds, just a bit smaller than a black capped chickadee were flitting about in the branches nearby. They were almost jet black. Definitely
