Nighthawks

I'll admit my birding skills are a little rusty, but I did spot a nice "group" - "flock" [kettle - I suppose] - of nighthawks on Saturday evening. It was about 6:00 pm and they were circling above my house moving slowly from the Northeast to the Southwest. There were about 12 or so. Up to now I've only seen single nighthawks, so I went into Google and searched circling nighthawks ramsey, and low and behold the first two posts were for MN sightings: This post from another Ramsey County birder, and this from a Dakota county birder.
