Prolly has to do with the young in the nest. That's my guess.
Or the crow has mental issues...
Years ago, when starting to build our house, I was doing some framing, and a crow came down and landed on my shoulder. I found it amusing.
He hung around for a few day, and at the time we had a CJ7 jeep with a hard top, and if we left the house he would land on the top of the roof and ride for a while, I guess until we got to a speed where he was kind of forced off the roof due to air pressure. I saw this when my wife left, and I was still at the house.
I remember one time going up the road about a hundred yards, and slowing down to make a left turn. There is a house at that point, and the woman was outside doing yard work, and the crow left the roof and flew over and landed on the woman's head.
I still laugh when I remember this. "I can't stand it, I can't stand it" she was screaming. Made the turn and never looked back...LOL
It was summer and no AC in the old jeep (not much of a heater in winter either)...so easy to hear what was going on outside...
