I know I'm going to feel foolish for asking this, but here goes!! I've seen these critters all summer around the wetlands and farnlands around Sacramento. I see them in flocks of 5 to 25 or more, usually late in the day as if they are leaving their feeding grounds (wetlands) to go to their roosting area somewhere else. The only species I can think of found in this area (that I know of, anyway) is White-faced Ibis. I see hundreds of them some days (total addition of several groups). I haven't been able to get a close look at them... this photo was taken from several hundred yards away, thus the poor quality. I'm hoping someone can ID them by their profile and location!
