Mixed flock feeding

I’ve seen mixed flocks of passerines bouncing through a forest, feeding on different vertical levels and plants, but hadn’t really ever noticed it among these waders and swimmers. There were probably over 15 Double-Crested Cormorants, a few Snowy Egrets and Great Egrets, about six Brown Pelicans, and a handful of passing Royal Terns, all cruising a small marsh creek entrance as the tide approached the morning high.
