Helicopter or Something Stranger in Robstown?

Someone reported a UFO sighting to MUFON of a UFO hovering over Robstown, TX (near Corpus Christi) - apparently it had white flashing lights and red and green on top. Could this be a helicopter or something else?

Watching in my back yard an UFO that has whit flashing lights under it. Red and green on top. Seems to be hovering over Robstown.
