Like an armada of great ships, they all suddenly appear.
They are always around but there is something that starts this ‘follow the leader’ game.
Someone considered perhaps their was a person feeding them. But first no one is here, at least that would. Second, who hands out food to these huge guys.
My guess is one leaves the reeds, others follow so they don’t miss out on something.
No matter what, standing there watching is a privilege.
Best viewed large, these are detailed, and some are hidden on the shore.
