“It is a seductive space of suction and vortex, of migration and wandering and swirl.  Open to sun, open to lightening, each day and step have a distinct uncanny potential for revelation.”   —  Richard Powers, The Echo Maker

We watched the sandhill cranes return from the fields to the Platte River, where they roost at night.  The shallow sandbars provide a habitat relatively safe from predators.  There were a few early cranes claiming their roosting spots, but as the sun set, more and more strings of sandhills flew overhead, seemingly rushing to find safe harbor  before dark.

We weren’t as close the these wild birds as I would have liked for intimate photographic portraits, but the opportunity to see such vast numbers in huge flocks was as special in its own way.

“In sandhill cranes the daily flights to and from roosts are closely tied to light levels. . . . Almost cetainly light levels, rather than sunrise or sunset per se, are the critical factor, for in the Platte River area the cranes always begin returning to the river before sunset on cloudy days, but often wait until a half hour or later beyond sunset on sunny days with extended periods of twilight.”  — Paul A. Johnsgard, Cranes of the World
