Your timing is funny with these coyote videos. I just had 82 pictures and videos of coyotes show up this week also. They are over a couple of days, but all while it is dark out. I agree that they are very leery of the infra red from the camera also. Their ears are moving like radar constantly also as they dip in and out like nervous wrecks. You can certainly tell that they a not at the top of the food chain out there.
Nice videos by the way.
