There was calm over the flock of cranes on the feeding ground. Many birds were foraging or performing maintenance activities. Pre-strut, strut and parallel walking (?) were very frequent. Many of the struts often in pair, never turning into, but possibly run-ups to parading, most often interrupted with ritual preening. Ruffle-bow-up/down very frequent, esp. ruffle-bow-down, I would say.
