Fledging is going on at the Boise nest. I couldn't see any of the chicks on the ledge today. From the site:
Update: Friday, 26 June
One of the chicks decided to go for it this morning. The youngster took its first flight and landed safely on a building located directly across the street. Clumsy and awkward at first, fledglings must practice how to judge distance and speed and develop a sense for safe places on which to perch. This is risky business, in both wild and urban settings.

Fledging has gone well so far for the female chick, the first to leave the nest. She did hit the side of Hotel 43 yesterday but got herself safely to a window ledge. A dedicated group of bird watchers has been observing her every move. The first flight was a rough one for the male, however. He fledged last night and collided with a car. He was taken to a bird rehab facility where he was well cared for overnight. The chick appears to be in good shape but Fish and Game biologist Bruce Haak will keep him for observation tonight and return him to the nest tomorrow. Observers are still waiting for the third chick to take her first flight.
