观察细节

Huge cloud, high over the marsh; tough to take photos in the rain (of the largest flock); photos of part of the flock when they swirled lower, landing in the bushes and taking off again. Murmuration. Estimate but we feel it’s conservative. We couldn't spot anything but tree swallows in the flock. Photos.
