Mississippi Kites breeding

I just realized that videos on my blog can be enlarged to full screen views (rather than having to go to youtube to do it) by clicking on that box in the bottom right of the video that has 4 objects (that look like arrows) in it.I spotted one of the Mississippi Kites fly from the nest to this more distant cottonwood followed immediately by the other apparently male kite. I saw them begin copulatory behavior but it took 10-20 seconds to move my tripod around to start videotaping so very short video clip doesn't show the entire sequence. SeEtta
