As I was maneuvering to a spot where I could view the wading bird feeding frenzy I spotted this small group of egrets off to the side. They seemed focused on something to my right; the big group was further back and to my left. The weren’t interested in joining in with the others. Perhaps they’d had their fill.
When the larger groups from the huge flock took off it was pretty noisy, mostly from the wing beats. During one of those lift offs this group decided it was time to move on.
