Albuquerque, NM— The signal that marks the end of summer sounds a little like the blow of many trumpets high in the sky above us. It is the sound of Sandhill Cranes migrating to their wintering grounds in the Middle Rio Grande Valley and beyond. During the day, cranes find food in open fields, foraging for seeds, roots, bugs, worms, toads, and small rodents. At night, cranes roost on open, shallow sandbars in the Rio Grande. Not just a season for sandhill cranes, other species of wintering birds can be seen in the Albuquerque area as well.
