I've been seeing this flock at the lake edge for a week. Finally got close enough to get a picture. Took a whole bunch of pics of them earlier in the week only to find out that I was only hitting the focus button and never even took one picture. The joys of MS, forgetting how to use something that you know how to use. The white one looks like an Ibis and am assuming that the darker ones are females. Anyone else have a guess?
