The news from Brooke Pennypacker, who is monitoring the Class of 2011 at the Wheeler National Wildlife Refuge in Alabama, is there has been a behavior change. Up until this past Sunday, the young cranes have been going to roost on their own in the evening. They continue to frequent the same spot during the day as the two Direct Autumn Release (DAR) cranes and a group of Sandhill cranes, but as evening approached, the three groups would depart and go their own way.

Brooke said the Sandhills generally begin heading for their evening roost site around 4:00-4:30pm; the DAR birds for theirs about an hour later. Then, around six-ish, the nine cranes in the Class of 2011 fly off to their favored roosting location. Monday that changed.

Beginning that evening, the Class of 2011 joined the Sandhills at their roosting spot, but in Brooke’s estimation, not until too much time had elapsed. You see, while the nine young birds altered their roost location, they didn’t alter their timing. They are still waiting until six o’clock or after before they make that move.

Brooke says this habit makes him nervous, and that he wishes they’d pick up on the roosting timing of their Sandhill cousins. He said, “I’d worry a whole lot less if they would get safely settled in a roost site earlier, because once dusk begins to fall, predators come out to hunt for their dinner. As it is, it’s getting pretty dark by the time they decide to call it a night.”

Isn’t that just like teenagers? When they will learn? Let’s hope they pick up on that survival skill lesson soon.
