Patilka 1948 39 Corvus corax Aug. 31 Santa Cruz Island, California Fair present about cliffs, moving back and forth between two outjutting ridges. Once they came to one of these and the larger of the two, presumed to be the male, perched about 15 feet below the other. He then performed in a manner never noted before by me. A series of four notes, hollow, deep, not loud, were folled by a series of three sharp notes apparently made by snapping the beak. Notes 1-3 rose in pitch slightly, the last dropped. To give these notes, the raven pulled his head in, bill pointed down, then riased his wings and plumage about the head slightly. As the four notes were given, the head was raised, wings dropped, into normal position. Then, following a slight pause, the bill notes were given. This performance was given three times separated by pauses of several seconds. The male then looked up at the female, took wing and repeated the performance twice on wing. The female called once, a mild, drawn out kraaa, then followed him. ku-ku-ku-kā kē.kē.kē seconds
