Will we see another egg?

Today about 2:30 the birds copulated on the ledge. Unfortunately, it was over before I could save an image and/or record a video clip. Mating doesn't necessarily mean an egg is on its way but we're all hoping there will be more eggs added to the clutch. So, I'll put this out there again as I did in my post after the 1st egg was laid: "Eggs are laid every 2-3 days...Peregrines generally lay a total of 4 eggs."

The second egg was laid Sunday evening, so 2-3 days would have us expecting another either today or tomorrow (Tuesday or Wednesday). If these birds only knew how many eyes were watching and waiting...!!!
