I am so lucky to live on this particular homestead. We have woods behind and south of us and a river out our front door. It is time for the migration through here of the cormerant. as I sit here at my desk in the dining room I can look out the front window at the river below. The cormerants start by flying in from downstream. Hundreds of them. They are very quiet. They fly low over the river and go upstream then a bunch of great blue harrons come flying down stream to take up their positions along the shore. Soon all you see comming down the river is a bunch of long necks sticking out of the water as the cormerants float down stream searching for food. They randomly dissapear below the water and pop up somewhere else on the river. This system of hunting drives the minnows toward the shore as they are swimming for their lives and the great blue harrons are waiting. after they have drifted far enough down stream one bird will rise up out of the water, run along on top flapping its wings until they are dry enough to fly. Then they will all start running on top of the water, flapping their wings till they gain a little altitude. They skim the water as they fly back upstream to start this ritual all over again. The only sound you hear is the running and the wing tips slapping the water as they go back upstream. We get to watch this ballet every Spring. I think that this system of co-operation between two different kinds of birds is awesome! We have a large harronry just about a half mile upstream. Usually they are hidden in the woods but this tree is in plain sight on the other side of the river. It has been there for many years. It was hard for me to pull myself away to go to the barn to do morning chores.
