2016.2 Incubation prolonged for week after week

Crane eggs should hatch in 30 days. Incubation began on May 6^th 2016, but the eggs did not hatch on June 5^th. Yet Millie and Roy continue to incubate night and day into mid-July as this report is written. We suspect that the embryos drowned when the nest was flooded during the heavy rains of mid-May 2016.

On evenings while Millie incubates on the nest, Roy stands in Bog Central and calls. Sometimes, he is answered by a pair of cranes across Goldstream Valley. Whether or not he is answered, Roy frequently flies out to land across the valley and then all three cranes may call back and forth. The conversations between Roy and the cross-valley pair suggest that there is local social structure among cranes in the valley. Perhaps valley crane pair includes one of Roy and Millie's colts from previous years?
