Accipiter cooperi. Maine (Lake Umbagog). 1874. Aug. 4. While skirting the edge of a deep and heavily-tim- bored ravine, my attention was attracted by a shrill whistling cry repeated at frequent intervals. Approach- ing cautiously I discovered four young Cooper's Hawks, sitting close together in a row on a fallen log; every now and then, one of them would raise his wings, and flapping them to maintain his balance, would walk a few steps along the top of the log, and at the same time uttering the whistle above described. They sat very erect, and, young as they were, had all that dignified, and stern bearing so characteristic of the family at large. Shooting one, the rest flapped up into the tree above, where I killed another when the two survi- vers disappeared. By the side of the log I found a half-grown Ruffed Grouse, neatly plucked, with the head and breast eaten. 1880. June 3. Several seen of late circling over the woods.
