Sandhill Cranes are the oldest living bird species with a lineage in the fossil record dating back some ten million years. Greater Sandhill Cranes are 4 to 5 feet in height and weigh from 10-14 pounds. Watch for them on the edges of wetlands and in open fields. They are omnivores like humans and feed on both green plants and seeds, vertebrates such as mice or frogs, and invertebrates such as insects, grubs and worms.
These are year old adult birds which will breed next year.
My thanks to Mike Meetz for the location of these birds and to Steve Dinsmore for input into the text.
