A couple of days ago it was simply glorious down by the river below our house. The recent high water levels were gone and the river was actually calm. That is Goat Island in front of us in the photo- this is where the Great Blue Heron rookery is.
A flock of birds seemed to come out of nowhere from behind the island. At first I figured they were geese, but if so then that was one very sloppy V-formation.
It was the herons! I hadn’t seen them fly together as a flock like this before. I imagine they’ll settle down soon.
