notes as o-onc-o-onc-ough , egh-ough-egh. Their flight is generally near 
the water, and when shot at while flying they sometimes dive from the 
wing. He also mentions their habit of towering, “usually in the after- 
noon, collecting in mild weather in large flocks if undisturbed, and 
going up in circles so high as to be scarcely discernible, often coming
