During the day, we saw the cranes feeding in groups as small as three and as large as several thousand. They feed in the corn and soybean fields along the Platte River. Generally they will range out less than 10 miles from the river. When food is scarce, they will go 15 miles if they have to. Huge numbers of snow geese arrive in the Platte valley before the cranes and have been reducing the food supply available to the cranes.
