As they started to fly to shore, they drew their feet up under the body plumage in front about at the rear end of the sternum. This I saw distinctly, a dozen times or more.

On one occasion a dozen or more Grackles chased the Hawk into some dense spruce wood. I saw them mob a Crow in similar manner. Thrice they in their turn were pursued by indignant Robins. Towards evening I noticed a Grackle who seemed
