single bird flew in from the west. Heard distintive nasal double "ah ah" once, followed by several single "ah" calls. Flew about 100 yards east and landed in oak tree. Continued to call. Bird moved east and assumed to be the same bird appeared again at 7:38am calling and then flew back west. Appeared slightly smaller than American Crow, with slightly longer tail (Seen in video). Uploading sound file. Birds calls at 1 sec, 7 sec, and 12 seconds.
