A migrating flock of some kind of Ibis few over me yesterday. If you enlarge this & look at one of the front birds, it appears to be eating a mid=-flight snack. Their bills are very distinctive but they were not close enough to get detail for specific identification, there are several different species of Ibis they might be.
