What are these chicks doing? On September 1, chicks #620 and 618 had a friendly sparring match. They are jump-raking without actually touching. That's good, because cranes have wicked claws. Do you see the "costumes" watching from a distance? How old are #618 and #620 in this photo?   Photo Chris Gullikson, Operation Migration   Journey North is pleased to feature this educational adventure made possible by the Whooping Crane Eastern Partnership (WCEP).
