As many as 36 cranes were seen over the weekend in the area of Cheyenne Bottoms and Quivira NWR in Kansas. The next days and weeks will see virtually all of the mid-continent flock arriving on the Texas coast, where they’ll be waiting on Gavin Bieber‘s February tour, Whooping Cranes and the Rio Grande Valley.
