All of the crows I have seen flap steadily, gliding only occasionally. [...] It could not have been mistaken even for the tails of the occasional American Crows that appear quite rounded. The sheer size of the bird and the wedge-shaped tail were enough to distinguish it from any of the crows, but what about the Chihuahuan Raven? Fortunately, as it flew by, the bird made two brief call notes that were very hoarse (sounding much more like grrrawgk than the gaw of the American Crow), and much deeper than the Chihuahuan Raven that I heard in northern Texas. However, because it has been a few years since I had seen or heard the Chihuahuan, I decided to double check the calls on a tape I had at home. The tape and I agree that the call was that of a Common Raven. \| The original documentation form event lasted from approximately 11:10:00/11:11:00.	Iowa Ornithologists' Union \| MS 166	12	47
