Black UFO caught over a hotspot in Windham, NY

On April 10, 2015, after visiting a local hotspot in Windham, New York, a witness noticed a black UFO on one picture. What is it?

Witness report:

I was with my brother George and his girlfriend Crystal in the year of 2015. We were visiting a local hot-spot on a summer 80 degree day called Point-Lookout, in East windham. Its known for its 5 state view, at now what they call it "The Captains Inn." What made us notice the object was afterwards once the photo was already taken. As we were looking right then and there in the spot the photo was taken in, were looking around in the sky to see if that object was anywhere in sight. Although it is clearly in the picture, there was not a plane, a helicopter, or anything i could possibly think of in the sky that day. I don't know how to explain it, but it wasn't anywheres but in the photo. I still obviously think about it till this day, Iv had other experiences but this one is by far the closest proof iv ever had and the only proof. The feeling i got afterwards was extremely intense, looking at the picture and then looking into the clear blue sky it just felt unreal. I felt the energy of being watched, or whatever that was knew when and exactly when that picture was taken and quick enough to disappear. It was very uncomfortable. Whatever this object was it was gone as quick as the snap of our picture. For the longest time its gone Unacknowledged.
