| Occurrence Remarks |
The documentation letter by Manit Bunnimit is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] It flew for most of the time by soaring with its wings held very flat, only twice flapping its wings momentarily (shallow wingbeats) and once folding its wings rather tightly and gliding. 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. |

| Event Remarks |
Viewing Conditions: [...] The sky was overcast so I did not have to put up with the glare during my observation. I immediately grabbed my 8X42 binoculars to get a closer look. The bird was flying fairly close, probably only about 70-80 feet (maybe ten feet above the crow in a nearby tree). There was only a very mild wind (5-10 mph?). |
