I'm glad you like the Falcon Cam, Marina!
She should be laying her eggs anytime. I just checked the second camera and she's in the back of her nesting box, away from the ledge.
(Here's a picture from the second camera.)
She seems to spend much of the daylight hours at the ledge, the evening hours towards the back of the nesting area, and late night back at the ledge. So I expect to see her back out at the ledge in a few hours. There is also a male falcon named Kinney. The falcon we see most of the time is KathyQ.
