Carla and Ecco now have four eggs but we wouldn’t have known it until sharp-eyed observer Scott Hannan captured a screenshot just before 7am when Carla and Ecco did a nest exchange. Ecco is in this photo, getting ready to incubate.

It took me a while to find the moment when Carla laid the egg. From the overnight archives she laid it at 1:20am. It’s under her tail in this screenshot.

Here’s the video at the moment of laying and a couple of minutes thereafter.

After laying the egg, Carla incubated nonstop until Ecco came to relieve her at 6:58am. Here’s what Scott saw this morning.

It is likely that this fourth egg is Carla’s last for the clutch. She and Ecco will be incubating until hatch date in late April.
