Morning breaks with warm rays of sun over cool blue light of dawn as Sandhill cranes (Grus canadensis) fly in to sit in two inches of precious Ogallala water on the Platte River. Grassland birds of the Great Plains migrate from Siberia and Canada to the southern United States and Northern Mexico. Their main migratory path is north-south and then in reverse as they fly in to breed in the High Plains aquifer. The birds path is constrained by the Rocky Mountains much in the same as the ancient aquifer. Birds depend on these protected waterways creating an hourglass shape in their migration making a wide path following to the narrow choke point at Kearney on the Platte River. Nearly a half million migrating Sand Hill Cranes fly in to Crane Trust property and adjacent farmland; Wood River, Nebraska, United States of America
