Sandhill cranes gather to roost in the Platte River in the midst of their migration. Cranes roost standing up in shallow water bodies where any approach by predators is quickly audible. Here, the weather was cloudy and dark until the sun came out for a few minutes at end of the day and created an arresting scene.
I came across this group of avocets feeding in a Bay Area harbor late one evening. It was interesting to observe the flock feeding in a circle. One avocet would dredge the bottom bringing up invertebrates and crustaceans, and the next member would move in to feed in that spot. The steady movement of the birds and low light gave a opportunity for an abstract.
