One morning while I was on school crossing guard duty, there were 3 sandhill cranes that flew into the field area of the school yard. one crane stayed outside the fence while the other two went inside. The one who stayed outside decided to walk across the street where I was standing.He stopped when he was less than 5 ft away from me.I am 5' 6" and that bird was as tall as I am. I didn't make any alarming moves and he got bored and rejoined his friends. They stayed in the field tille the kids started arriving for school and then they flew off.
