It really isn't . The start flying at 5:30 am & heading North for there morning hunt . they all always go out in at the same time . I have photos of some 200 going out at the same time . In fact just took some photos of the coming back from the hunt just soaring on the wind . In fact had to take three are fore photos of the flock ,because didn't have my wide angle lens . So when I got home I put them all together in one photo so you could see just what I saw ??
