I was well aware of this, and like other committee members, I believed that they were likely present in this area. I can only say that I was watching the birds when I heard them, which eliminates the possibility that they were young American Crows. I would not want to rely on the morphologic features. I was impressed that this group stayed together in the flooded woods, which was unlike the behavior of the American Crows. \| The original documentation form event lasted from 08:40:00/09:30:00 and 10:25:00/10:35:00.

Bunnimit, Manit	Common Raven	Lake Manawa State Park	[...] Lake Manawa State Park, near Council Bluffs, IA. [...] was travelling south on the road that follows the west edge of Lake Manawa.		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.	Iowa Ornithologists' Union \| MS 166	12	47
