Flocking Committees!

I was sitting in bed this morning with a mug of tea, watching the birds out of the window, when one of the flocks of Lapwings (or Green Plovers or Peewits if you are so inclined) muddled into view.
They seem to be birds of committee status... or a collections of politicians.

They were flying to the right... initially.... but then two decided to head back the way they'd come.
A few more followed them and then the rest of the flock...

First they flew to the right....

then they flew to the left...

No, wait.... at least three haven't followed... they are ploughing on steadily towards the right.
About turn the rest of the flock... they'd decided.

...then to the right. Again!

But...
they had not yet come to a firm decision...
one, then a further two, then a group started to fly back the way they'd come...
and again the rest of the flock followed...
everyone this time!

No... a breakaway group from the middle went right this time! Followed by....

...the rest!

This happened about four more times... before, quite suddenly, as they were all flying left, as one they turned and flew strongly off to the right and disappeared behind the trees.

A few minutes later a smaller group flew left to right without wavering at all.
Flocking committees!*

There's always a rebel in any committee!

*A committee is a dark corridor up which ideas are lured and quietly strangled!
