The cranes began incubation on May 18. They alternate shifts, which range from 2-8 hours. Millie passes her off-duty time by bathing and feeding.
Every day, Roy calls and listens for answers from other cranes nearby. Every day he files on excursions into the valley, perhaps to check up on other cranes who are summering in nearby marshes.
Roy defends the nest, in one case from a pintail duck that came too close.
Both cranes feather paint during this time and wander their territory while the snow and ice melt.
Hatch was on the 30th day (June 16, Father's Day in 2013). One colt, who we named Pi, was soon following Roy and Millie as they foraged.
