UFO at Obama's Inauguration

Is this a UFO at Barack Obama's Inauguration? At around 12 seconds into the video, a small object appears by the Washington monument and zooms across the screen. People have speculated it may be a bird, but it seems like it moves much faster then a bird would. It also appears to be pretty large, although it is far away on the camera. At any rate, this definitely fuels the fire on the "Government coverup theory" and cast a dark shadow on what was a good and historical day for America.
