#70 Sandhill Crane
In one of migration’s great spectacles, more than half a million Sandhill Cranes gather annually along central Nebraska’s Platte River from February to April, fattening up in cornfields before journeys that may take some as far north as Siberia to breed. Birders flock to the Platte to see their courtship dances and to hear their strange bugling calls. Sandhill Cranes mate for life – which can entail two decades or more – and the pairs stay together year-round.
