I know you FRIAM'ers are fond of flocking behavior:

Really impressive. A while ago my daily commute took me out past the
rice fields south of Houston. Once a year we would see migrating 'rice birds' in a 'contiguous' tube-like flock stretching from one horizon to another while rising above the hedge rows. (But that was before digital cameras.) The flock might drift from side to side but the birds just kept on coming and coming and coming. These flocks too showed a sharp boundary between relatively evenly spaced birds to none. What's the story behind boundary effects/observations I wonder.

Absolutely fantastic! A lot of synchronized trajectories, and possibly some oscillation patterns between higher and lower density formations.
One almost wonders if there is communication occurring at a holistic level, between groups as complete units. It seems there is collision avoidance between some of the groups, which might be indicative of group communication, although it is hard to tell. But there is also a lot of integration between groups which might counter the possibility of collision avoidance on a group level. Just a few thoughts.

Reminds me of single cell organisms moving across a microscope slide. The ebb and flow of endoplasm as the cell moves and changes directions.

Thanks, they're stupendous! It's obviously all in their minds,
though... there's just nothing else at play. I don't have any idea how to ask them what the big issue is! These are very different from the ones I was thinking of when I mentioned flocking as an extraordinarily beautiful complex system phenomenon. These seem to take on very clear fluid flow characteristics, the regular spacing between individuals and the serpentine lava lamp like gyrations of the groups. The ones I was remembering had some of the same kinds of soaring groups but not the uniform spacing and more evidence of individuals or small groups splitting off and then others pealing off to join them until some large piece had separated.
