Mysterious UFO!

A much larger Mother Ship was right above and these small light looking things appeared as if to be checking certain places and then they all disappeared. I caught one on Tape. Any ideas? But then I caught another one on Tape.

I thought it was a one time occurrence and then it Happened Again. I could hear a strange humming noise coming from above and there had to be something large there but nothing was visible when a Mockingbird flew into it and fell straight down dead. Then another spread of sudden odd Lights covered the area. Then they quickly came and disappeared.
