UFO hovering above vicinity of local park.

Waiting for a bus. Spotted UFO immediately hovering over vicinity of St. Clair Reservoir Park. Took six pics on iPhone 6s. Distracted enough to not think of taking a video. After about a minute or two, two groups of young men came along sidewalk and gathered to wait for the bus. We talked briefly and no one could come up with an idea of what it could be. The head and tail were changing colour from blue to green. The head at times looked like a v-shaped jet plane and then would morph and go out of focus to more of a blob shape. Sometimes the head was a bright white colour and then it would change to the same colour as the tail. The tail was moving somewhat and had separate lights within it. Advised by admin. of UFO UpDates to report it.
Update from witness: This has been explained as a kite with leds.
