UFO Hawk Flying Sideways

While watching coverage of a grass fire in Rancho Cordova at around 4:40, July 3 2017, I saw a weird black shape fly out of the smoke. This is the type of thing that would be classed a UFO, but luckily the cameraman followed the shape and zoomed in, revealing it to be a hawk. The curious sideways motion seems to be a parallax effect from the movement of the helicopter. Video Source: More discussion:
