Unison Call

Young Sandhill Cranes begin participating in the family unison call at about two years of age. Females raise their head to about 45 degrees and return to the horizontal between calls while males usually raise the head to a more nearly vertical position.

From the above I would deduce these 5 cranes comprise a mated pair and a second mated pair with their first year juvenile offspring.
