As usual, E2 incubated the eggs yesterday afternoon while Dorothy took a break at the Cathedral of Learning. After she finished her snack she came back to take over incubation duties, but he was reluctant to leave.
She arrived at 3:18pm and asked him to get up, but E2 just looked at her and stayed put. Thirty minutes later Dorothy was still asking and it was starting to get funny. I got emails from Karen Lang and Rob Protz urging me to drop what I was doing and start watching.
By 3:55pm Dorothy's frustration was quite apparent.
"Get up! It's my turn."
Finally at 4:00pm E2 reluctantly allowed a changing of the guard.
Watch a slideshow of their interaction and the measures Dorothy had to take to get him off the nest.

p.s. The webcam has some spots on its weather-proof cover so E2's face is sometimes obscured, as in the photo above.
