Photos I've taken over the last three years in central Nebraska of the Sand Hill Crane migration. Every spring over 500,000 sandhill cranes migrates through central Nebraska. The roost overnight on the sand banks of the Platte River. Each evening hundreds of thousands of sandhill cranes leave the surrounding cornfields and almost simultaneously take the flight to roost in the Platte River. It's an amazing "audial" and visual experience.
